About `TypeVar`, passing a `name` keyword argument to `name` keyword and positional parameter gets error

*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.

Start by running the reported mypy test.py example with mypy 1.19.1, then compare its result with Python runtime behavior and pyright in strict mode. Trace the TypeVar call handling and add a regression test for TypeVar(name='T'); done means mypy accepts the keyword form without regressing positional handling.
