The following code should successfully type check:

from werkzeug.datastructures import TypeConversionDict

d: TypeConversionDict[str, str] = TypeConversionDict()
x: int = d.get("a", default=1, type=int)

However, mypy gives an error:

$ mypy error: Incompatible types in assignment (expression has type "Optional[int]", variable has type "int")
Found 1 error in 1 file (checked 1 source file)
