Summary

Noticed this while messing around with astral-sh/ruff#22111. If you have a name from a different module also defined in the current module, inserting an inlay hint can cause a name collision.

module.py:

class A: ...

main.py:

from dataclasses import dataclass
import module  # Don't import A directly because there's also an A here

class A: ...

@dataclass
class B[T]:
    x: T

b = B(module.A())
# After inserting, oops
# Object of type `B[module.A]` is not assignable to `B[main.A]`
b: B[A] = B(module.A())

This is most common for me with Literal, since sometimes I do just want a Literal in my parser, but could happen with any name.
