I wonder if we can catch cases like these where elision breaks things.

Basically, when the returned value has no relation to the inputs, lint that elision might not be wanted.

Exact heuristics would be tough to figure out, but I think it's doable (I've got a rough idea)

Ideally this should go into the compiler, but we can start it as a lint.

Since lifetime elision's gone a long way from 2014 to today, is this still an issue?
