Method invalid_type

mypy/fastparse.py:1899–1911

Constructs a type representing some expression that normally forms an invalid type. For example, if we see a type hint that says "3 + 4", we would transform that expression into a RawExpressionType. The semantic analysis layer will report an "Invalid type" error when it
