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

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
  - 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

lizmat so it's looking up the parts in the setting ?

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.
nine That's got to be my most favourite commit title of all time :)

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)
