Before bringing the language change proposal, it makes sense to implement the feature and test it out on real examples.  MSVC compiler implemented a number of coroutine features to do sanity testing and put in the customers hands before a feature was proposed.

Since this is a non-breaking change, I think it makes sense to put it in and play with it. This particular approach was talked about since 2014, but, no formal proposal was made. I am bringing the paper to upcoming Jacksonville meeting and would like to make sure that we have both implementation and usage experience for the feature.
