Rust Keyword Generics Progress Report: February 2023

The group working on adding keyword generics to the Rust language is
foreshadowing what it plans to propose:

A main driver of the keywords generics initiative has been our
desire to make the different modifier keywords in Rust feel
consistent with one another. Both the const WG and the async WG
were thinking about introducing keyword-traits at the same time,
and we figured we should probably start talking with each other to
make sure that what we were going to introduce felt like it was
part of the same language - and could be extended to support more
keywords in the future.
