    Of all ways to put a file's lines in an array, I'm afraid that is one of the most inefficient. Moving data from INSIDE a do { } block to OUTSIDE a do { } block requires copying it, so you're making a list and checking it twice, so to speak.

    If I REALLY needed to put a file into an array (why, I do not know), using the above trick, I'd do: 
    my @lines;
{ local @ARGV = $file; @lines = <> }

    But why should the file be in an array? Ick.
