Re: Anonymous multi-subs

I'll just note that you can fake anon multi subs with lexical subs like
this:

my $sub = do {
    proto foo (|) { * }
    multi foo (Int $x) { $x + 1 }
    multi foo (Str $y) { $y ~ 'a' }

    &foo;
}

say $sub("hello");

The sub there is still named "foo" as attested by $sub.name, but isn't
available under that name outside of the do block.
