in thread strict or not strict?

Of course 'replace all' was my first thought, but then I did think of the above method and just wanted to investigate further down this road.
Hence my question...
Thanks for your help.

    If the variables are declared already above your loop, then you can do it via string eval. E.g.

    #!/usr/bin/perl use strict; use warnings; my ($blah, $boo, $hoo); # DECLARED HERE my %data = ( "blah"=>1, "boo"=>2, "hoo"=>3 ); # assign each key to a variable of the same name foreach (keys %data) { eval " \$$_ = \$data{$_} "; } # end-foreach print $blah; exit;

    Replace is still probably a better long run strategy.
