Pyright’s constraint solver retains literal types only when they are required to satisfy constraints. In other cases, it widens the type to a non-literal type. Mypy is inconsistent in its handling of literal types.
```python
T = TypeVar("T")
def identity(x: T) -> T:

def func(one: Literal[1]):
reveal_type(one) # Literal[1]
v1 = identity(one)
