That wouldn't be very useful; object.__str__ exists and is functional,
so EVERY object would count as a string.

The point of "string-like" is that it can be treated as a string, not
just that it can be converted to one. This is exactly parallel to the
difference between __index__ and __int__; floats can be converted to
int (and will truncate), but cannot be *treated* as ints.
