[Haskell] State Monad

[Bruno Oliveira]

Hello,

Can somebody point me out the exact CVS location of the State Monad implementation
that ships with GHC? I am a bit lost in the CVS directory structure ...

Related to this, I saw the following thread:

http://www.mail-archive.com/haskell@haskell.org/msg17702.html

Which seems to hint that there are 2 alternative implementations for the State Monad:
one lazy version and one more strict version. Is this correct?

What I am really trying to find out is if the version that ships with GHC is the strict 
version. At least I am inclined to think that, since a program that I expected to 
terminate is not terminating ...

Finally, if there are indeed two versions, can somebody write (or point me out) the two 
different implementations.

Thanks,

Bruno
