-The syntax depends on the kind of implementation. For example, we could want the type system to be valid Python and use Python classes, functions and annotations. In that case, the syntax would be quite restricted by the available set of valid Python expression which don't affect have a direct effect on the program.

 Moreover, if we do use Python's builtin syntax, there could be two approaches: either define real Python classes and functions in Python, or simply use the syntax and parse it externally, without any real Python semantic.
