I have, and I'm -1 on it:  it's largely a copy-paste-small-edit of massive
portions of dictobject.c.  If it has to be implemented via massive code
duplication, there are less maintenance-intense ways to do that.

freeze-on-hashing was pioneered <wink> in the Python world by kjbuckets.
I've used it in my own Set code for years without particular pain.  Greg
Wilson seemed to hate it, though.
