I wholly agree with that. Perhaps a different name would have less
stink. "uses_return_value?", perhaps? Or maybe "needs_return_value?".
I think that's a little more descriptive, to boot; it lets you know
there's a little magic going on behind the scenes.

I am still unsure as to whether this would be a good idea, I haven't
run through all the potentials for abuse yet. And i don't know if it
would even be possible to implement.
