The old behavior was to raise an exception, but Django was catching
the exception and doing unexpected things. For instance, in the
manage.py shell, printing out a ModelReprMixin object (with
__unicode__ not implemented) would result in nothing being printed,
rather than it raising a error or otherwise alerting the programmer as
to what was going on.
str_utils.py has functions for converting strings from one type to
another. It also has a TypeVar called NonBinaryStr, which is like AnyStr
except that it doesn't allow bytes.
