I gave a talk about this one two years ago on YAPC, and the punchline
for this JAPH is: "The question is not what it does, but why does it
compile?".

Being a newbie, I am very curious about what the heck is going on in those
few lines. Is there an online reference to that talk and if not, would you
mind explaining it a little.

I think the one you are asking about is discussed in the former talk.
