Optional chaining support?

[dead-claudia]

I'm thinking this, to align it fully with object methods.

• receiver?~>fn(): receiver == null ? undefined : fn.call(receiver)
• receiver~>fn?.(): typeof fn !== "function" ? undefined : fn.call(receiver)
• receiver?~>fn?.(): receiver == null || typeof fn !== "function" ? undefined : fn.call(receiver)

I agree that optional chaining would be a logical extension of this proposal. The next time it gets presented to the committee plenary, I might raise it as a possible extension. Since the Committee tends in my experience to be conservative and incremental with regards to syntax, it might deferred to a future proposal.
