Quadrilingual Crazy Programming

It's neat, but...

First off, this guy obviously has much better kung-fu than I do...I've never even heard of BrainFuck or Befunge...but I think he kinda cheated on the last two languages. He just hid the code for Brainfuck and Befunge in perl and C comments, so they wouldn't interfere with each other. Now, the perl/C part is really neat, because he used C #defines to translate various Perl characters into C, so the Perl interpreter and C compiler are reading and understanding the exact same code...that's cool. But the B & B code just gets ignored by the Perl interpreter and C compiler because of comments, so this amounts to writing 3 seperate programs (one in BrainFuck, one in Befunge, and one that's bi in C and Perl) and then putting them all in the same file with intstructions as to which compiler/interpreter reads which part, as opposed to writing one piece of code that's meaningful in all 4 languages. I'd call this bilingual, not quadlingual.
