RakuAST: give correct error message when accessing non-existing package variable

lizmat So making progress on getting declarator docs working 13:42
token comment:sym<#|> {
'#|' \h $<attachment>=[\N*]
{ nqp::push(@*LEADING-DOC, ~$<attachment>) }
}
nine: any idea why that would be called 3 times when just having:
#| This is a sub
sub a() { }
ah, this only appears to happen at the compunit scope 13:45

RakuAST: fix package subs not found before their lexical location in code

Fixes: Foo::foo; package Foo { our sub foo() {} }		 14:31

RakuAST: fix package variables being VMNull before their lexical location

Fixes: Foo::foo; package Foo { our $x = 1; our sub foo() { $x.defined } }
lizmat nine: re pod strings: I wonder whether we really need to make them all StrLiterals 15:23
the result of all pod strings is basically a big WVal array in $=pod 15:24
[Tux] where is "where" documented for "multi method foo (Int:D $x where ...)"? (I want this case to only allow 0..5) 16:04
I scanned docs.raku.org for "where" but to no avail 16:05
lizmat docs.raku.org/language/signatures....onstraints 16:06
[Tux] So my guessed "(Int:D $x where { 0 <= * <= 5 })" should be correct 16:08
[Coke] you need $_ there, inside the {}s 16:11
m: sub x(Int:D $x where 0 <= * <=5) { $x.say }; x(-3) 16:12
camelia Constraint type check failed in binding to parameter '$x'; expected anonymous constraint to be met but got Int (-3)
in sub x at <tmp> line 1
in block <unit> at <tmp> line 1
[Coke] without the {}
you can use the *
lizmat m: sub a (Int:D $x where 0 <= * <= 5) { }
camelia ( no output )
lizmat m: sub a (Int:D $x where { 0 <= $_ <= 5 }) { } 16:13

ugexe Should github.com/rakudo/rakudo/blob/bd08...m6#L88-L89 should start with `my $!;`? 16:47
there are a couple of other instances of checking global `$!` after a `try` in there as well 16:48

RakuAST: initial stab at integrating declarator blocks

  - Add X::Syntax::Pod::DeclaratorTrailing::MissingDeclarand error
   class to mark trailing declarator doc that cannot be attached to
   anything
  - Add tokens for #| #|(...) #= #=(...) declarator docs to grammar
  - Add associated methods to actions

lizmat gist.github.com/lizmat/24de913b31b...7c4e422c10 so is this a trailing declarator doc bug ?? 18:32
Geth rakudo/main: a930b3ba2f | (Elizabeth Mattijsen)++ | 2 files
RakuAST: multiple calls to tokens are apperently normal

The legacy grammar had a way to make sure that each leading or trailing declarator doc was only added once. Copy the same mechanism into the Raku grammar		 18:59

Tap

Bar::Foo
lizmat so it's looking up the parts in the setting ?
m: say Q|class Bar::Tap { }; say Bar::Tap.WHO|.AST.EVAL
camelia ===SORRY!=== Error while compiling
Confused
------> class Bar::Tap { }; say Bar::Tap.WHO⏏<EOL>
lizmat meh 19:14
nine Lexically: 19:15

RakuAST: fix wrongful stealing of stashes

With multi-part package names, we could have found the final part of the name lexically and then went on to steal that totally unrelated package's WHO.		 19:54
nine That's got to be my most favourite commit title of all time :)
lizmat hehe 19:56

RakuAST: fix .raku of Rakuast::Doc::DeclaratorTarget objects

Creating a .raku representation of object 1 that has an object 2 as an attribute, that has object 1 as an attribute, it is a bit of a challenge to prevent infinilooping.
This adds a "declarator-docs" method to DeclaratorTargets, which ... (7 more lines)		 19:58
