implicitly return is so stupid, give the choose to user.

[gamergamer8888]

don't restrict culture

if your app has much void function, like web,
you must add return; to every last line, that's so ugly.
explicitly return is better

otherwise, bla, bla, bla

convenient is the best
please use ^-> or other syntax to add return; auto
