Hey,

I came across this document discussing explicit/implicit lifetime extension
which sounds really interesting, especially the Polymorphic lifetime
analysis part.
Has there been any news about this proposal? The paper has some interesting
motivating examples where the current lifetime extension is quite limited.
One example in particular deals with "ranges", since I guess we could
expect ranges in C++20 (I really hope :)), I am wondering if it isn't right
to actually deal with this issue.

Best Regards,
Paul
