1) a declaration as 

  object: b

Wouldn't break the original idea, since b would be basically a python
object as it is now.

2) Sure a declaration as

  int: a

would break the original idea, but that was just given as an example
of what kind of declarations one might possibly use. You are not obligated
to use declarations that limits you so much.

No I wasn't answering that. I was just trying to give an idea from
a different angle. People seem to think that one uses static typing
or inheritance typing or duck typing. IMO the possibility of inheritance
typing doesn't have to prevent duck typing.
