Feature: void return

[edef1c]

A void return a la JS's return void EXPRESSION would rock. Maybe !return EXPRESSION or return! EXPRESSION.

[vendethiel]

something like EXPRESSION; return ?

EXPRESSION; return ?

This, or if you must: return void expression

[edef1c]

That works, though not quite idiomatic. I do if (cond) return void expr a lot in JS, for short-circuit logic.
return! expr if cond would be awesome.

[vendethiel]

That's actually a more common patrern than I first thought, reading node code. if err then cb err; return is what I'd use (return void expr gets aci => return void, expr; and I'm not sure I'd like to see more hushing syntax).

[edef1c]

return cb err if err is very common, along with a variety of similar async dispatches.
return! expr could compile to expr; return (return void is the best we can do when writing JS straight, but we have the opportunity to improve here)

[satyr]

Hmph. True that it is another case forced more verbose than JS.

Options:

1. Reuse the hushing analogy as proposed: !return (and not return)
2. Treat return void (currently useless being the same as just return) as one operator.
