Unable to specify a default value for a generic parameter #3737
Description
Simplified Example:
from typing import TypeVar
_T = TypeVar('_T')
def foo(a: _T = 42) -> _T: # E: Incompatible types in assignment (expression has type "int", variable has type "_T")
return aReal World example is something closer to:
_T = TypeVar('_T')
def noop_parser(x: str) -> str:
return x
def foo(value: str, parser: Callable[[str], _T] = noop_parser) -> _T:
return parser(value)
