When using containers one can choose to use std::vector::operator[] or std::vector::at. Similarly, using std::future::get could get a non-checking/waiting variant with std::future::operator(), Personally I would prefer this because calling std::future::get in a then-lambda just looks wrong (semantically) because in my head this get function is associated with (possible) waiting/blocking. -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
