We didn't bother with this in the regular compiler because it doesn't change the generated code. In the stand-alone compiler, this can clutter the output with useless variables. It's especially bad after functions are inlined but the foo_retval declarations remain. v2: Use set_foreach. Suggested by Tapani.
