I run this script:

use strict;
use warnings;

my @lines = (
"Once upon a time",
"scrooge & donald",
"went for a long walk"
);
my @list = ("huey", "dewey", "louis");

foreach my $who (@list) { 
    my $sub = "\$ln =~ s/scrooge (& donald)/$who \$1/g;";
    print "$who\n";
    foreach my $ln (@lines) {
        eval $sub;
        print "$ln\n";
    }
    print "\n";
}

[download]

and I get this:

huey
Once upon a time
huey & donald
went for a long walk

dewey
Once upon a time
huey & donald
went for a long walk

louis
Once upon a time
huey & donald
went for a long walk

not what I was expecting. Anyone help?
