Path validators: I am not sure if we check this, but stuff like super::super::foo or use foo::{crate::bar}; should be forbidden.

These are still up for grabs if anybody wants to get their hands dirty and contribute something small but useful!

The relevant code is currently in crates/ra_syntax/src/validation.rs. The existing validators should serve as decent examples, but please don't hesitate to ask how to go about it, if you're interested in giving it a go!

I'll take a crack at this over the next couple of days.

@chuck-flowers, did you already start? I am also working on this, though not very fast ...

[chuck-flowers]

I haven't done much yet

[Veetaha]

@chuck-flowers I am not contributing very fast, but I suppose this issue is not the most important one since it was opened more than a year ago and I already learned a decent amount of codebase around ra_syntax where the validation occurs.
Well, maybe, might you tackle some other issue to avoid conflicts with my changes? I also have some unfinished work to do on the previous refactoring...

[chuck-flowers]

No problem. I can find something else to work on.

Okay, thanks )
