I think C++ designers are fully mad, this shows how to use C++ lambdas:

If D2 lambdas (and closures) become *half* complex as that I'm going to stop
using D on the spot :-)

Well, they're somewhat limited, and a bit manual, and actually just a
syntactic sugar, but otherwise they're quite close to D's stack
delegates, even in syntax.  I couldn't see what scared you that much.

 Anyway, I'm impressed that MS is getting these things into the
 compiler so quickly.  I had expected to see another C99 foot-dragging
 extravaganza.  Guess it just goes to show how little they care about
 C.


The discussed features are really a significant improvement for C++
productivity.  I think a lot of C++ code is still being written by MS so
improving productivity here should be a priority for them.

I wonder if there are any chances for typeof() in C++.

C++ is a .NET language now ;-P

I think it's mostly the capture mode [] stuff that's a bit ugly.
I think this is a legal lambda:  [=,this,&x,&y](int& r) mutable { ... }

It's called decltype().
