Thanks. That helps some.

Changing the code to the following:

#!/usr/bin/env perl

use strict;

my $s = 'eabcde';
my $t = $s;

print "$t\n";
$t =~ tr/abcd/efgh/;
print "$t\n";

print '*' x 4, $/;

my $search = 'abcd';
my $replace = 'efgh';

$t = $s;
print "$t\n";

eval {
   $t =~ tr/$search/$replace/;
};

print "$search\n";
print "$replace\n";
print "$t\n";

Gives me the results: 
eabcde
eefghe
****
eabcde
abcd
efgh
epbade

I don't see why the results of tr/// differ.
