ksn00b How is it possible to use enum within 'given'/'when' scope? 00:01
ksn00b This is my code: pastebin.com/QKXKdJay 00:04
MasterDuke tbrowder: something like this perhaps? `for $pod -> $_ is rw { $_ = pod2text($_) }; my $string = $pod.join("\n\n");` 00:24
tbrowder thanks, MasterDuke, I'll try that! 00:43
Zoffix .tel ksn00b yes, `when` can smartmatch one an Enum. Your issue was you used commas inside the `<...>`. The angle brackets already separate on space; no need for commas. Also, enums can start at values other than 0. Also, `when` can be used without a `give`. It smartmatches against the topic (the $_ variable). gist.github.com/zoffixznet/1fe5397...0785b0dd87 01:01

zengargoyle if somebody could tell me whether this is a bug or just some other misunderstanding i would much appreciate it. :) 01:36
ksn00b Zoffix: ah.. That was my mistake, thanks. 01:44

timotimo zengargoyle: not only does the one with the whatever star match "only the last", it'll match the last as many times as there are matchers 01:48
timotimo looks like it's not closing over the $r as much as you were expecting, and i'm not sure what amount of closing is to be expected here 01:48
more likely the regex compilation isn't closing over the $r as much as you're expecting it to 01:50
i should really go to sleep before the damn birds start yelling at me again
zengargoyle so the additional -> code is somehow makes $r more closed. why doesn't this affect the eq version as well or is it just some regex thing. hrm... 01:53
zengargoyle heh, maybe it's just a fluke that the eq version works in the first place. :) 02:00
tbrowder all: thanks to kurahaupo's word description and MasterDuke's hint, I think a long-standing bug in Pod::To::Text may be fixed. it now successfully extracts pod from S26-documention.pod without error. I will submit PR tomorrow. 02:19

Zoffix How to get symbols the module exports via EXPORT sub? 13:05

MasterDuke or like the examples from the discussion from yesterday. subset My-Int of Int where ... . constant My-Array = Array of Int 22:18

camelia Type check failed in assignment to $x; expected MyType but got Str ("123_456!!!")
in block <unit> at <tmp> line 1
jnthn Heh, I see raiph and I took the alternative interpretations of the problem. :) 22:20
beginner AlexDaniel : we have built in types like int for numbers ,str for characters. I need to create a type that is combination of number and symbols
raiph beginner: if a dynamically checked type is OK then I think creating a subset type as demo'd above is the natural solution 22:23
beginner thanks all...that helps 22:24
mscha m: sub foo(Int @bar = (1,2,3)) { say @bar }; foo; 22:41
