That's an enjoyable and educational read, thanks!
There's one form under TMTOWTDI that I'd like to see, but can't figure
out myself. It's the version analogous to this perl5 snippet-
sub odd {$_ % 2}
say grep odd,0..6;
-where the line that filters the list mentions no variables at all,
and "$_" does its work behind the curtains.
perl6 golfers, what can you formulate- using anything you like in the
"odd" sub, not adding to the Int class, not using anything with a
sigil in the filter expression? I haven't figured out how to match
p5's brevity yet.
