no, it's not.  it's not like that at all.

as michael pointed out, we've already added a *third* way to access
type objects in 2.2.  you're adding a *fourth* way.

string methods were added at a time when Python went from one to
two different string types; they solved a real implementation problem.
reducing/eliminating the need for the string module was a side effect.

or as likely, part of a slow, long-term effort by to make Python
totally unusable for any serious software engineering...
