Blocks in C, not C++

I will note further that the Lambda feature in C++ has different syntax from Blocks, and there will be strong pressure, particularly from implementers, on the C committee to match the C++ Lambda syntax, i.e. using "[]" where Apple's Blocks uses "^". (Ironically, "[]" looks typographically more like a block, and "^" looks more like a lambda.) I expect Apple to support both syntaxes in the end.
