What features do you think it needs, that wouldn't spoil the "elegance" of the language? I think one good feature would be higher order messaging, in fact there's already a PL paper discussing how it looks like in objective-c [1] which would add FP-like filter/map elegance that all modern languages have. This would go nicely with simpler "JS lambda" style block syntax to make functional-style programming easier in objc.
