I'd follow the example of let, begin & friends: the last expression's
result is returned.  If there are no expressions, it's undefined.  Seems
fairly straightforward to me--at least, I cannot think of any reason
_not_ to have it behave thus.

Perhaps there's a good reason; I don't know.  But it seems to me that
returning the result of the last expression would make sense.
