	Code that has been returning str8 becomes much more apparent thanks to this (e.g., struct module returning str8 for all string-related formats or sqlite3 passing in str8 instances when converting objects that had a __conform__ method). One also has to watch out in C code when making a key from char * using PyString in the C code but a str instance in Python code as that will not longer compare equal. Once str8 gains a constructor like the current bytes type then test_modulefinder needs a cleanup as the fix is a little messy in that file. Thanks goes to Thomas Lee for writing the patch for the change giving an initial run-down of why most of the tests were failing.
