Thanks for the help, Isaac.  I didn't know how good of a job GHC did
when optimizing code like that.  I don't have a problem with that code
I wrote as a rule (it doesn't look ugly to me), but I just wanted to
make sure my binding didn't cause crashes.  I like the liftM2 thing,
though; I think I'll go with that.

Thanks,
Rob
