in thread counting backward

Four orders of magnitude more memory, or a minus sign. My choice is simple; how about yours?

I'll use minus sign until perl5-porter optimizes foreach reverse rangeop

Or i'll use for;;;

    It's a shame you can't use the c-style for as a modifier:

    cmpthese -1, { a=>q[ 1 for -1e6..0; ], b=>q[ for( my $i=1e6; $i; --$i ){ 1 } ] };; Rate b a b 14.0/s -- -26% a 19.0/s 35% --

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.
