I agree.  The more I looked at it, the more it became clear that
__slots__ turns a class into something very non-pythonic, with
significantly different behavior.  A lot of utilities, debuggers, and
advanced programming tricks will be coming with this disclaimer:
"does not work with any class which defines __slots__"

Unless you absolutely have to have it, don't use it.
