*Memo:

• mypy test.py
• python test.py
• pyright test.py # Strict mode
• mypy 1.19.1
• Python 3.14.0
• Windows 11

The doc of TypeVar indicates name parameter is both a keyword and positional parameter as shown below:

class typing.TypeVar(name, *constraints, bound=None, covariant=False, contravariant=False, infer_variance=False, default=typing.NoDefault)

But with mypy, passing a name keyword argument to name keyword and positional parameter gets the error as shown below:

*Memo:

• No error occurs at runtime.
• pyright gives no error even with strict mode.

from typing import TypeVar

          # ↓↓↓↓↓
T = TypeVar(name='T')
# Error

error: TypeVar() expects a string literal as first argument

So, mypy should accept a name keyword argument.
