Inspired by a user question. Jason, thoughts?
Since C++ is such a moving target, Microsoft have /std:c++latest
(AFAICT clang does not), to select the currently implemented version
of the working paper. But the use of 'std:latest' is somewhat
ambiguous -- the current std is C++20 -- that's the latest std, the
next std will more than likely but not necessarily be C++23. So this
adds:
-std=c++current -- the current std (c++20)
-std=c++future -- the working paper (c++2b)
also adds gnu++current and gnu++future to select the gnu-extended
variants.
I like this direction.
I imagine people using these to mean roughly beta and alpha, respectively.
Perhaps we also want -std=c++stable, which would currently be equivalent
to the default (c++17) but might not always be.
