in thread My favorite looping mechanism in Perl is:

Uh...why?

Personally, I find for-as-foreach more useful:

for my $i(0..$#array) { #same thing as your C-like for stuff; }

@HPAJ=split("", "rekcaH lreP rentonA tsuJ"); print reverse @HPAJ; #sucky but who cares?

    Personally, I find for-as-foreach more useful:

    Try make:

    for my $i (0 .. $#array) { ... }
    efficiently do something like:
    for ($i=0; $i < @array; $i += ROWSIZE) { ... }

      oh, you mean like

      for my $i ( grep { not $_ % ROWSIZE } 0 .. $#array )

        Yes. using foreach you have to do something terribly contorted and crazily inefficient. Like that.

        Thank you for so adeptly illustrating my point.

        That would do ROWSIZE mods and ROWSIZE comparisons plus some other junk in place of a single addition.
