How about instead of freezing, just modify a flag or counter if it's 
mutated.  That could be turned off by default.

Then have a way to turn on an ObjectMutated warning or exception if any 
objects is modified within a routine, code block. or function.

With something like that, small parts of python can be tested and made less 
mutable in small sections at a time.  Possibly working from the inside out.

It doesn't force immutability but instead asks for it.

A small but not quite so impossible step. (?)
