sisar Hello. After I'm done using a user defined operator, how do I de-define it ? 06:54
FROGGS[mobile] sisar: let it go out of scope 06:55
06:55 lizmat left, lizmat_ joined
raydiak yes better to define/import it only in the scope where you want it 06:56
FROGGS[mobile] or you can perhaps delegate to CORE::infix<foo> but well, that's not quite clean 06:57
06:58 skids left
sisar ok. i'm not sure I undertand what do you mean by 'delegate to CORE::infix<foo>'. What is that ? 06:58
is 'CORE' a special namespace ? 06:59
FROGGS[mobile] yes
useful if you want to implement an existing op by using the existing one 07:00

sisar what is this 'CORE::' thing ? 07:02
FROGGS[mobile] the place where the built ins are defined 07:03
raydiak the way I heard it explained before is it's basically all the names you can see which are not defined in your own code but techincally exist one scope level outwards
sisar ah. ok. 07:04

sisar *operators
raydiak no but you could mask them out with another one
sisar hmm. but masking correctly might mean that i need to think very carefully about masking all the aspects of how that operator works. Can't i just delete the op, and start from a 'clean slate' ? 07:08
raydiak if you are able to, I'd bet that anything which makes us fast like optimizer, JIT, etc, won't like it at all 07:09
sisar .oO ("Can not remove values from a PseudoStash" is an LTA reply by the language, methinks)
.oO ( or maybe it thinks, if you are mature enough to know CORE, then you are mature enough to know what a "PseudoStash" is.) 07:12
raydiak of course another approach would be to do whatever it is you're trying to accomplish as a slang instead
if you're poking at them without knowing what they are, giving you the name to look up in the docs is probably helpful 07:14
(pseudostashes that is)

perhaps yes
[Tux] that is what I found yesterday
FROGGS Nil does not disappear anymore in lists, and that causes trouble now
[Tux] and as Nil is not dropped from list context anymore, I found that behaviior consistent
FROGGS I expect that the Nil/Empty transition is not over yet and will take weeks 09:00
[Tux] if the statement is as you claimed "assigning Nil to something restores it default value", '@x = Nil' should equal '@x = ()'
[Tux] will follow evolution as close as possible :)

yes yes
lizmat pmichaud just said he sees Empty as temporary scaffolding during the GLR 09:13

But I'll have it straight in a day or two.
The other news in GLR is that I think immutable iterators need to go away

it needs a stage0 update so I don't want to push many of these to a branch 09:22

masak is there any advantage of `submethod BUILD(...) { self }` rather than just `submethod BUILD(...) {}` ?
I'm not aware of one. 13:21
itz there is no -shared target for linenoise.so you have to compile manually and move into either the current working directory or a LD_LIBRARY_PATH location
lizmat I guess it's part of a non-standard .new ?
masak could very well be. this was in Enum.pm, and when I changed `method` to `submethod`, I got an error in the vicinity of Pair.pm, a subclass. 13:22
pmichaud in looking at the linenoise details, I think I'd much prefer having linenoise linked in at the nqp level. There's already nqp::readline() defined, and HLL::Compiler.readline as well. 13:23
masak blib/Perl6/BOOTSTRAP.moarvm originates the error. it expected a BUILD in Pair -- didn't find one. guess until now it's been inherited.
13:23 coffee` left
masak yep, the `method BUILD` in Enum is non-standard, alright. it takes two positionals. didn't notice that until now. 13:24
lizmat masak: yeah, just discussed with jnthn
we're cheating there 13:25
masak starting to realize that.
guess because Pairs are needed to have positionals in the first place.
13:25 ssqq_ joined
masak er, to have named params 13:25

[TuxCM] gist.github.com/Tux/fceeab1d62fc77c00382
pmichaud the outer block is in sink context (due to the ~$e.say following it). Since that block contains a CATCH, it acts like a "try block", and executes its contents in sink context. The value of $e is being returned in the first case, so it gets sunk. In the second case it's the "1" that is being returned from the CATCH, and it gets sunk also (but is more quiet about it) 15:05

raydiak yeah FROGGS was the first to suggest you could probably at least define it to point to something useless or nonexistant, but I didn't figure out if/how that would work and what it would look like, and didn't much care for the messiness anyway so moved on 17:23

raydiak but by then I was pretty tired and my attention was just kinda floating around uselessly, so I wasn't even keeping track of the original problem I was trying to solve any more :) 17:26
timotimo right, we don't expect you to reimplement "say" to something that you don't need to supply an argument to

raydiak FROGGS: yeah that one was a mistake, I meant the "unsupported use of bare ..." 17:46
FROGGS ahh yes, that's a check in the grammar 17:47
skids That check seems aimed at heading off bareword errors for perl5ers. And in the way for other folks. 17:50
Hrm, or no, why is that check even there, really? 17:51
raydiak he was on to an idea though...if you could get a "no-CORE setting", or something closeish to it, it'd be a fun way for people to try their toy languages without even needing their own grammar, just relying on the *fix op declarations 17:52

skids Though I guess a policy of "if P5 decides to backport this sub from P6, do not allow bare use" might be appropriate.
raydiak it'd be cleaner I'd think to just have a "multi sub say () { die ... }" in core, but it has a runtime penalty 18:12
