Non-sensical Compiler Suggested Fix

help

I ran into this trying things in the playground. It returns a non sensical suggested fix. Did a quick search and didn't find anything. Is this known bug or should I file an issue?

I'd file an issue with a minimal reproducible example personally. I don't know what the correct behavior is, but it's certainly not that.

Though nightly does have a suggestion with valid syntax, which leads to GATs

I was pretty sure I had fixed this recently and indeed it is fixed in nightly: Rust Playground
