Brilliant and magnanimous Apple team adds closures ("blocks") to C (8)

Both GCC and Clang, though the code is still relatively untested.

Obviously, this is extremely non-standard, but check this out:

So there's a chance Blocks could make it into C1x.

Isn't this called Objective C?

Closures not objects. Presumably, Apple wanted closures in Objective C, but the languages are similar enough that making the feature available from plain C was trivial.

shit syntax, and no, it won't make it to the C1x standard.

Yeah, I think it's unlikely they'll show up in C1x, but not because of the syntax, but because of the reliance on some underspecified allocator and mmu protection bits problems.

Closures are SORELY needed in Objective-C! This is great news on that front.

The syntax does look really painful, though it could just be the fever and alcohol and lack of sleep... (And does it even make sense to have this in plain old C?)

Anyone in this thread read Stes' 1998 proposal for Obj-C? (It's not comparable, since it didn't deal with C, but anyway.)

C1X you say! I can hardly wait until 2019 rolls around.
