I don't fully understand lambda calculus, but i inferred a stack overflow from his tattoo?

Went to buy the book and its beyond my budget at the moment ($215 on Amazon).

It's a tattoo of the call-by-name Y combinator.

You'll get a stack overflow in a strict language, but not a lazy one.

$215? When I clicked through to the book, I see "Available from these sellers. 9 used from $597.95"

WTF?!??

Click on the hardcover edition link.

Aaah, I see.

Still, I give a big "WTF?!??" to the idea of paying $597 for any version of this book. I mean, I'm sure it's a good book, but $597 worth????

Heck, even $215 seems a bit crazy.
