Bismark has asked for the wisdom of the Perl Monks concerning the following question:

I'll admit that I am probably getting way ahead of myself, but I have been looking at some of the obfuscation and some of it is just driving me crazy. Would someone please give me some hints as to how the following code could print out JaPh? I understand how it is printing, just do not see where the letters are coming from.
"Yet what are all such gaieties to me
Whose thoughts are full of indices and surds?"
