I think it's ok to treat the return statement as sort of an exception.
You could create an actual exception and raise it instead, but in such
a small function that clutters up the code unnecessarily. At most I'd
add a comment near the return statement, mentioning that the finally:
clause will clean up the dialog.

That old separation was just an artifact of how the parser was
originally written, I believe. It was always considered an annoyance
and it finally got fixed.
