Support for 'std::optional' #313
Description
The function rc::gen::maybe lifts a generator into the Maybe monad, which can be quite useful.
C++17 finally introduced its own version of Maybe to the standard library, namely std::optional.
Would there be any interest here in a submission that provides support for this addition to the language for compilers that can support it? rc::gen::optional, perhaps? If so, I'd be happy to contribute.
Cheers,
Jonathon
