`defer()` arity

[s4y]

Hey,

It turns out that Socket.IO looks at the arity of callbacks (LearnBoost/socket.io#268) and deferrals always have an arity of zero. (Some other JS libraries use functions’ arity too.)

It would be cool if deferrals had the right arity. I have a workaround which looks like this:

await …, ((cb) -> (arg) -> cb(arg))(defer(arg))
await …, defer(arg) # instead of this

Any suggestions on how to implement this? On Nov 10, 2012 10:44 PM, "Sidney San Martín" [email protected] wrote:
