region name resolution, early vs late bound lifetimes

[nikomatsakis]

It'd be nice to make this concept obsolete someday. Until then, here is some discussion from Discord on the topic:

region name resolution, early vs late

[mark-i-m]

I came across this: https://gist.github.com/nikomatsakis/fe440aec437f7e8ad4cce8319954a973
and the related discussion: https://rust-lang.zulipchat.com/#narrow/stream/144729-wg-traits/topic/reintegrating.20chalk.20into.20rustc/near/190518417

Would be good to include the info about early/late bound generics and why the difference exists.

(Also, @nikomatsakis discord links break quite easily, so in future it would be great if you copy into a messy gist or hackmd and link that instead, sorry).

Hmm, I didn't know that Discord links break easily! Maybe I'll go back to my UUID technique of making links. =) (Embed a UUID one can search for)
