Rename lint to something else

[brson]

It has outgrown its original purpose and is becoming the general error reporting mechanism.

Is this still a relevant issue? It doesn't seem to me like it's a general error reporting mechanism any more. I think of span_err/span_note/span_warn more along those lines. The lint module in my opinion does indeed have true "lint" passes for code like unused variables, mutability, imports, and assignments.

I'd personally be in favor of keeping it named lint, but I could also do the renaming if there's a better name!

It isn't error reporting, it's specifically warnings, that aren't about invalid code. Closing, as it no longer seems relevant.
