in reply to strict or not strict?

I'm trying to plug a hash into an old piece of code (for a once off) and I was hoping not to have to change every instance of i.e $blah to $hash{'blah'}. Just being lazy...

Replace All is your friend, surely? That or write a one-liner to replace it for you ...

    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.
