I have a patch that adds a new function to the gc module.  The gc.remap() function uses the tptraverse mechanism to find all references to any keys in a provided mapping, and remaps these references in-place to instead point to the value corresponding to each key.

The motivation for adding this method is to enable writing a module that provide an enhanced version of imp.reload.  The builtin reload function is very useful for iterating on a single module within the Python interpreter shell, but in more complex situations it very limited.

Is there any reason that you'd want to do this?

Please let me know if you have any feedback on the reloading proposal, the hot loading prototype, or on the patch.

Overall, I think this adds lots of backwards incompatible code for an obscure use-case that will cause subtle and complicated bugs. So, -1.
