I totally do not understand the requirement for the dictionary and its extra overhead.

Under your proposal, annotation consumer libraries have to provide wrappers for Python's built-in types, since the only way a library has of knowing whether it should process a given object is by applying a subclass test.

Extending this same idea to static analysis tools, tools like pychecker or an optimising compiler would have to supply their own such wrapper classes. This would be a huge burden, not just on the authors of such tools, but also on those wishing to use these tools.

I want people to be able to use Python's built-in types without ugly wrapper classes or any other similar impediments to their pre-existing Python workflow/thought patterns.
