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

Re^4: when $$s =~ m/\G.../gc is too verbose (for) by TimToady (Parson) on Feb 03, 2006 at 19:10 UTC
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.)	[reply]

Much like in English, you can use Perl's `for()` for iterating over a list, iterating via initialization + check + step, or associating a single topic with a block of syntax. So I, without apology, use `for()` for topicalizing. For you, I won't stop doing this. (: Excuse me for not demonstrating the use of English "for" analogous to init + check + step. - tye	[reply]
