TypeVar stub is incorrect

https://github.com/python/typeshed/blob/master/stdlib/3/typing.pyi#L13

Should be something like:

class TypeVar(object):
   __name__: str
  def __init__(self, name: str) -> None: ...

[JelleZijlstra]

Is this causing a concrete problem for you?

[peterhal]

Yes - the following doesn't type check:

def f() -> Any:
  return TypeVar('x')

Worth noting that the same with the other type constructors (List, Mapping, Optional, ...) all work fine.

I am not sure whether changing it in typeshed will help, since type checkers tend to ignore typing.pyi. That said, I am in favor of having typing.pyi match reality as best as possible anyway. Patches welcome!
