Not sure slice[1::3] can be done

It can be done. Since "slice" is a class, it would require a metaclass though.

Another solution that nobody has mentioned (as far as I know) is to add additional syntax to the language for that. For example, one could say that (1:3) could be used to construct slice(1, 3) directly. The parentheses are required to avoid confusion with type hints. I'm not a Python language expert, but I don't think that type hints can occur inside parentheses like that.
