* iskeywordonly : bool True if the parameter is keyword-only, else False. * isargs : bool True if the parameter accepts variable number of arguments (\*args-like), else False.

How about "vararg" as its named in AST.

* iskwargs : bool True if the parameter accepts variable number of keyword arguments (\*\*kwargs-like), else False.

Can the "is_" be dropped? It's quite ugly. Even better, since these are all mutually exclusive, they could be cascaded into a single "type" attribute.

* isimplemented : bool True if the parameter is implemented for use.  Some platforms implement functions but can't support specific parameters (e.g. "mode" for os.mkdir).  Passing in an unimplemented parameter may result in the parameter being ignored, or in NotImplementedError being raised.  It is intended that all conditions where isimplemented may be False be thoroughly documented.
