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 )

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

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

        Thank you for so adeptly illustrating my point.
