This to me implies that postcircumfix:{'',''} returns some

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-

Hello,
The following construction doesn't do what a user might expect:
for 0...@foo.elems - $k { do_something($k,@foo[$k]) }
Obviously, the intention is to step through every key/value in @foo. Buf

I was wondering why the perl5 example didn't work in p6- $_ is a
contextual variable,
so why doesn't the body of odd get its $_ value
from grep in something like this:

If you make it a formally declared sub, then you have to
