snake-case-type-alias (PYI042)

Derived from the flake8-pyi linter.

What it does

Checks for type aliases that do not use the CamelCase naming convention.

Why is this bad?

It's conventional to use the CamelCase naming convention for type aliases, to distinguish them from other variables.

Example

from typing import TypeAlias

type_alias_name: TypeAlias = int

Use instead:

from typing import TypeAlias

TypeAliasName: TypeAlias = int
