Steven Bethard <[EMAIL PROTECTED]> added the comment:

Subclassing dict seems like a bad idea. The options value returned by
.parse_args() is not supposed to be dict-like, it's supposed to be
object-like. That is, the natural way of accessing values from it is
through dotted attribute access, not dict-indexing access. All the
documentation for the module makes this clear. Giving it both attribute
access and dict-indexing access would violate TOOWTDI. The One Obvious
way to get dict-indexing access from an attribute oriented object is
already vars().
