pmichaud hmm.
S32 defines .base but apparently it's NYI in rakudo.
lue Sure I could create my own sub to do it myself, I just think P6 should be able to go both ways [I don't recall such a function ever existing]
pmichaud S32 says .base should work on any Real

pmichaud either way works :)
lue so &base is a method inside the Real role? I feel like implementing it [but first, other stuff to do :/] 00:08
pmichaud it could be a method in Num, and Real delegates to it.
benabik How do you throw something in nom? die?
pmichaud yes, die works. 00:10

pmichaud Real is a role
Num does Real

crked Hi perl6, can I ask a question on perl5 ? 02:10
Someone else asked me and I really cannot figure out. It's about the perl -l usage with the here-doc structure 02:11
When I do perl -l <<EOF then $a = 1; then EOF. It seems the $a will be interpreted by bash first. 02:13
But when I do perl -l <<"EOF" the result is correct
I really don't know the difference between perl -l <<EOF and perl -l <<"EOF"
I am using perl 5.10
lue crked: I've never used Perl 5, but I know from using the Perl 6 commandline that using single quotes should keep bash from interfering with the variables. 02:17
Have you tried #perl ? That's a much better place to ask Perl 5 questions if you haven't tried that already.

TimToady it's probably useful to be able to pattern match an exception as a string 05:37
PerlJam TimToady: can a single block have multiple ENTER phasers? 05:40
TimToady yes
PerlJam and they are executed in which order?

TimToady S04:1380 05:42
PerlJam that doesn't say anything about execution order :)
TimToady no, but it was originally stated in A4, iirc 05:43
entering stuff (ENTER, BEGIN, START) happen in order declared
exiting stuff happens in opposite order

sorear ENTER should be pretty easy though. I think niecza had ENTER pre-mm
PerlJam sorear: well, you can re-add it and update perl6.org/compilers/features and be ahead of rakudo in yet another area :) 06:05
benabik With control exceptions, I'd think that LEAVE would be something that catches return exceptions, calls the block, and rethrows. 06:07
PerlJam not just return exceptions though
TimToady you'd think, but that's not when LEAVE runs
benabik True. All exceptions, I guess.
TimToady it runs at stack unwind time
which is after any exception is handled 06:08
so it's only the stack unwinder that has to care
benabik P6 is specced as using stacks? Can't implement with CPS? 06:09
TimToady well, just do anything non-idempotent in a LEAVE :)
*don't
06:10 wtw joined
sorear benabik: cps is really a kind of stack if you squint right. A linked list stack. 06:11
TimToady so like, only close files in GC, not in LEAVE ;)
benabik sorear: So "stack unwind time" is "call continuation time"? LEAVE would wrap the caller continuation with a "call this block first" one? 06:12
PerlJam there's a GC phaser?!? ;-)
TimToady yeah, called DESTROY :)
sorear benabik: stack unwind time means when an exception has committed to not being resumable 06:13
benabik But LEAVE is called at both exception and return time, yes?
sorear: Well, then you're wrapping the "exception failed" continuation. ;-D
sorear benabik: exceptions are not built on continuations 06:14
unless they are
benabik If you're writing a compiler with CPS they should be.
TimToady in that case stack unwinding is also a form of GC, and you can't do it till the lower continuation is thrown away :) 06:15
basically, you shouldn't be mixing transactional commits with continuations that refuse to commit 06:16
maybe we should allow Shroedinger Files to be both open and closed at the same time :) 06:17
I note that Ruby is de-emphasizing continuations these days 06:19
continuations are problematic unless you can carry hypothetical universes along with them
benabik If I understand CPS correctly, then you should have a both a "commit" and a "abort" continuation for something that's supposed to be transaction like.
06:20 kjeldahlw joined
TimToady well, but in the case of a deep continuation, you need something more like "commit" vs "uncommit" 06:20
"Ha, ha, I didn't *really* close that file..." 06:21
06:22 drbean joined
benabik The real trick in CPS is passing around and wrapping the continuations properly. Whether things aren't saved until "commit" is called or things are undone when "abort" is called is really an implementation choice. 06:22
TimToady CPS doesn't really mix well with mutable state, and filehandles are mutable
all the mutable state must be inherent to the continuation for CPS to work well 06:23
06:23 Su-Shee_ is now known as Su-Shee
PerlJam needs some sleep before work (~6.5 hours from now) 06:23
I guess my ENTER adventure with nom will have to wait until later 06:24
PerlJam .zZZZ
TimToady much like we do with Cursors in perl6 grammars, where the mutable state is carried along with the current Cursor, and thrown away if you throw away the Cursor
night, PerlJam
benabik It's more that you need to ensure that any cleanup is called with all continuations. But you run into the same problem in any non-linear control flow. Early returns and exceptions do the same thing. 06:26
TimToady it almost makes you want to have an IO monad... :)

gfldex looks like pugs wins in this case 12:12
moritz return types don't participate in MMD
no, it conforms to an outdate spec
gfldex what is the reason for that spec change? 12:13
moritz yes, computability
what if test() was a multi with one Int and one Str candidate?
gfldex it would be ambiguous and should trigger a nice error message 12:14
moritz multis make it impossible to determine what context a routine is called in
gfldex that makes the return type of a multi pretty much useless 12:16

moritz that doesn't do what you probably think it does
p6eval rakudo 922500: ( no output )
flussence I can see that :)
I'm surprised it's not a syntax error though
moritz it tries to call a method named 'a' on $_, which is Any
but since you say .?a, it doesn't error out when it can't find that method
flussence oh, makes sense.
would main{something-goes-here}.*a() work there? 12:22

flussence wondering if the .? .+ .* syntax would work on normal subs
moritz well...
