Sorry, I meant "restrict" as in having it stated that the annotations are for typechecking, rather than attempting to support a dozen different uses simultaneously. The annotations would still be free-form, with the semantics up to whoever's implementing the typecheck function, and Python itself wouldn't take any steps to enforce what can or can't go in the annotations.

-1. Th annotations should be available for whatever the user wants to use them for. Remember, lots of folks do not use shared frameworks -- the only framework they care about is the one they write for themselves, and they should not feel guilty about using annotations for whatever metadata they need. To take up an old rule from the X11 world, the language should provide mechanism without policy.
