in thread how to dynamically declare a varialble?

Ahhh. I missed the phrase "matched memory variable". I will reply again.

Your solution is poor - much better is to assign the matches to an array.

    Well it depends on what do you do. If you have code like this: 

    if (/regexp/) {
 no strict 'refs';
 my $i = 1;
 while (defined ${$i}) {
   ...
 }
}

    then it's definitely better (and fairly easy) to change the code and assign the matches into an array. If you have something like: 
    $text =~ s{regexp}{
 no strict 'refs';
 my $i = 1;
 while (defined ${$i}) {
   ...
 }
 ...
}ge;

    it ain't that trivial.

      Show me an example of the second and I'll show you how to rewrite it. The second sounds like someone trying to be too clever.
