in reply to A small (for me) JAPH
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.
