Description
Sorry, I know the title is hard to understand. An example will make much more sense:
// foo.gleam
pub type Foo { Bar }
// ^^^ (a)
// main.gleam
import foo.{Bar as Bar}
// (b) ^^^ ^^^ (c)
pub fn main() {
let _ = Bar
// ^^^ (d)
}
To reproduce: Move the cursor over (a) and trigger a rename to a new name.
Expected outcome: (a) and (b) change to the new value, (c) and (d) remain unchanged.
Actual outcome: (a), (b), and (d) change to the new value. (c) remains Bar. However, since (d) changes to the new value as well, the rename causes an unknown variable error at (d).
