Huge thanks!

I think the next step is to port the essence to typing_extensions, which has to 
work for anything from 3.5 up (or maybe 3.6), *including* 3.10 and above.

https://github.com/python/typing/tree/master/typing_extensions

Honestly maybe we could just make ParamSpec an alias for TypeVar there, and 
make Concatenate an alias for Tuple?  Because "work" just means that the syntax 
needs to be valid, the type checkers are responsible for using it. (We're still 
working on getting this to work for mypy.)
