Well, don't forget that the assignment to str *shadows* the built-in
rather than replacing it, so there may be places (imported modules being
the example that most readily springs to mind) where that replacement
won't be effective.
Plus which in CPython the C parts of the code may well be creating and
expecting objects of type str but they won't use the Python naming
mechanism at all, so you will have no way to effect changes in those
behaviors.
This will probably account for about 95% of any strangeness you see, but
it's probably a good first step in the conversion process.
