Can anyone explain the rules of placeholder attachment? i.e., in the
example in Perl6::Placeholder's manpage,
grep { $data{$^value} } 1..10;
C$^value is clearly intended to attach to the outer closure C{
$data{$^value} }, not the inner closure C{$^value}. But how does the
compiler know

It's easy to just say don't nest placeholder-using closures, but that
doesn't seem workable in practice since every block is a closure, unless
placeholders are forbidden from all but the most trivial cases. Absurdly
trivial, it seems. How about
$sub
