You might want to look at the optimised code with perl -MO=Deparse:

Spoiler

print $JAPH if $_ = 'Just Another Perl Hacker,' and
               $main::{join '', /\b\w/g} = $main::{(split(//, $_, 0))[
+2] ^ chop $_};

Nice use of symbolic references and ^...

The xor part reminds me of my own $A++ under constraints.
