I was trying to come up with an interesting example but failed. I actually _do_ want to do translation. (I'm writing a little crytpogram helper tool.) I want to replace all the letters from an alphabet, say $a, with all the letters from the new alphabet, say $b. 
# the alphabet
$a = "abcdefghijklmnopqurtuvwxyz";
# i've discovered that a represents T in the cryptogram, for example
$b = "T     E                   ";

$c = "the text i want to decipher";

$c =~ tr/$a/$b/;

So basically, is there any way to get this to work? Thanks for your help.
