Print an array one element per line, with line numbering - Perl Circus - Perl Tricks, Tips And Traps.
in a foreach (@array), $_ *refers* to the element being looked at in an iteration. writing to $_ modifies the element in the original array - update in-place. This enables efficiency if passing the array around for stages of processing, rather than working with copies - and also ensures that the original data is updated (if that's what is required)
