[cfe-dev] clang++ and Lambda expressions

[Michael Price - Dev]

Lambdas use a slightly modified form of the new function declaration  
syntax.

There is also the issue of capturing lambdas in a variable. Since the  
type of a lambda is compiler generated (I believe) it will be most  
common to use the auto typename, which I have a patch for (I just  
haven't gotten around to writing the tests).

After auto, the function declaration syntax was next on my list, but I  
rarely have the time to work on it all.
