I couldn't find any meaty discussions on this topic, so maybe it's
worth a post.

Does it make sense to use yield at the end of a function, where you're
essentially
using yield to replace a return value?  For example:

def returnfoo
  return foo
end

vs.

def yieldfoo
  yield foo
end

I see a lot of ruby programmers doing the latter, but consider the
former to
be more straightforward.  There are a lot of cases where yielding is
more elegant
than return, but I don't consider this to be one of them.  Anyone care
to weigh in?
