I've read a lot of the Monad tutorials, and I feel like I only get "most of
it" to be 100% honest.  The State Monad still boggles my mind a little bit.
 I understand what it's supposed to do and I get the idea about how it
works.  It's just that when I look at the implementation of >>= for it, I
want to crawl into a corner and nibble my fingers.

Ok, it's not that bad, but I'll admit I've gone cross-eyed a few times
trying to keep all that state in my head about what's REALLY going on there.
 Perhaps if it were pulled apart step by step I'd have a better
understanding.

I even tried to implement it once, and failed, however, I never seem to fail
to be able to *use* it if someone already implements it for me :-).  Kind of
like how I know how to operate a car, but I wouldn't trust driving one that
I built :-)
