Well, "right" is a highly subjective term, and I think it's a bit
foolish to say that a language as widely used, and widely-useful, as
Python, isn't "right".  But in Py3K, we're talking about what could be
improved, and there are *facets* of Python which could better support
its use.  I think method namespaces are already OK; the question is
whether to move these specially-named (for whatever reason) methods to
a real namespace (a dict somewhere), rather than using this
name-mangling kludge to introduce one.  If they're special methods for
the VM, as Ivan implied, let's put them in "PythonVM".  If they're
what operations and built-in functions call, let's use the "operation"
namespace suggested by Calvin Speakman.
