your sub swap can be written without $t:

sub swap { my ($i,$j) = @_; @a[$i,$j] = @a[$j,$i]; }

    lol, you bother to look upon this old piece of code :))

    heh, of course that your snippet is good, but a swap routine could be written even simpler:

    sub swap { reverse @_ }
    ... heh, it's not the case for that code thou, as the array is a global one :) cheers.
