I think that misses the point. It was more a general question with a "trivial" example

BTW I was on perl 5.6.1
I installed 5.8.4 (and a boatload of modules - thanks CPAN) and did a time comparison

Code used:
#!/usr/bin/perl
use Time::HiRes qw(gettimeofday tv_interval );
use strict;  # good habits start at birth

my ($start,$stop);
my @moo;
@moo = (1 .. 1000000);
$start = [gettimeofday()];
@moo = grep {; {if ($_ % 2 > 0){ 0;last; } 1;}}  @moo;
$stop = [gettimeofday()];
print tv_interval($start, $stop), "\n\n";

[download]

results:
5.6.1 did pretty much the same as 5.8.4

PS: anyone figure out why I needed the ';' in between the squigle brackets for the code blocks?
