[tpm] how to resubstitute a captured value

[Dave Doyle]

didn't know about the s///ee trick though. I had done this:

#!/usr/bin/perl

use strict;

my $match = '^-?(.+?):?$';
my $replace = '"-$1:"';


while (my $line = <DATA>) {
$line =~ s/$match/eval $replace/e;
print $line;
}

__DATA__
stuff
-stuff
stuff:
-stuff:
