in thread when $$s =~ m/\G.../gc is too verbose

That's why I wished Perl allowed another keyword as yet another synonym for for/foreach — I'd propose "with", for example:
with($$s) { ... }
But in the meantime, I've trained myself to actually read/see
for(SCALAR) { ... }
as
with(SCALAR) { ... }

Chalk it up as another Perl idiom.

    It's called "given" in Perl 6 (or in Perl6::Switch, if you want to play with 6ish topicalizers in Perl 5).

    Perl 6 also has syntactic relief for the m/\G.../gc monstrosity as well. That turns into m:p/.../, where the :p tells it to start matching at the current position. (But generally you don't even need that since subrules in a grammar always anchor to the current position anyway.)
