According to TimToady on #perl6, :{ $^a <=> $^b} is an
adverbial block (see S02).
So, I'm guessing the :{...} should be parsed by the
<postcircumfix> option of the <colonpair> rule:
token colonpair {
':'
[
| '!' <ident> {*} #= false
| <ident> $<val>=[ <.unsp>? <postcircumfix> ]? {*} #= value
| <postcircumfix> {*} #= structural
| <sigil> <twigil>? <desigilname> {*} #= varname
]
}
We may still need to find out what causes the parsefail in
Rakudo, though.
