type IntOrX = int | X

class X:
    pass

Configuration

No response

Command used

pylint --py-version=3.12 asdf.py

Pylint output

asdf.py:1:20: E0601: Using variable 'X' before assignment (used-before-assignment)

Expected behavior

No warning

The value of the type alias is evaluated in the annotation scope. It is not evaluated when the type alias is created, but only when the value is accessed through the type alias’s value attribute (see Lazy evaluation). This allows the type alias to refer to names that are not yet defined.
