[cfe-dev] Blocks vs. C++ lambda's?

[Remy Demarest]

Well, yes and no...

For starter, Apple's syntax doesn't need you to say anything about  
capturing variables, they're just captured. The [=]{} seems to be  
equivalent with normal variables, their value is copied inside the  
block's structure and it's constant.

But I was talking about __block variables. You add "__block" in front  
of a variable declaration and then you're allowed to modify its value  
inside the block, and that change is mirrored in every blocks in the  
same scope that capture that variable, too.
