Thanks everyone. I feel sortof like a dope since I
knew that to save the results of a function, I'd have
to save it in a variable. I just forgot in the
excitement of trying to use all the functions in the
same line.
Someone, I believe Jenda, brought up that the "useless
use of lc" was a warning,

Two things here:
1. It is pointless to lc a numerical value, and the boolean value [1 if a
newline was removed, 0 otherwise] returned from chomp will always be expre

You're confusing functions that return values (like lc) with functions

lc() takes a string, turns the string to lower case, and returns that. So
what you're searching for is:
chomp($input = lc());
This way, lc() function turns the input into lowercase, assigns it to the
$input scalar, and then chomps out the newline at the end. Quite efficent.

Using Benchmark.pm ... the answer is to use lc ... if you flip through to the

do changing of case (or at least tr/A-Z/a-z/ since it will miss accented

lc can handle locales where upper and lower case isn't the same as A-Z vs a-z.
