All of the examples you propose have non-standard behaviors,
introduce ambiguities, and only serve to confuse users.  There's
no good justification for any of the examples you present.
In _my_ HO, all of them are examples of bad design, and it
would not be such a bad thing if the standard Python option
parser made it very hard or impossible to emulate them.
