The most important implementation-based question that hasn't been answered here is what exactly can go in the {} part. Is it just variable names in scope, similar to how lambda capture lists can only name variables? Is it arbitrary expressions (and therefore potentially including lambdas that can resolve to statements?) I imagine that the former will be a lot easier to implement than the latter. -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.

Nic= ol, what are your thoughts on Florian's suggestion?
In the interest of grounding ourselves (although = I'm getting quite excited here), does anybody from the compiler communi= ty have any input as to any stumbling blocks in the implementation of this?=

Implementation of what, exactly?

T= he most important implementation-based question that hasn't been answer= ed here is what exactly can go in the {} part.
