Using Benchmark.pm ... the answer is to use lc ... if you flip through to the
Perl Cookbook pg 19 or receipe 1.9 you will find that tr is the wrong way to
do changing of case (or at least tr/A-Z/a-z/ since it will miss accented
characteers and so on..)
THe reason you are getting the error is because you did not capture lc's
return value. unlike chomp lc does not work on the argument and the return
value is the converted string ...
