Sometimes I think a _defacto_ standard is as good... when there's
only one implementation for something in Python, as perhaps with,
say, XML-RPC, that seems to make it as good as a standard.  At 
least it does for me.

Is there more than one OpenGL package available for Python?
If not, I'd call the existing one another defacto standard.
If someone else creates a competing API (and often the
question of "why do that?" would arise if the initial
choice was good) then we lose our standard.

Presumably whatever the one for Java does... :)

He probably would insist that there be only *one* API
for it to be "standard"... another red herring perhaps.

Another thing Python does: it wraps existing standard APIs for 
things with thin layers than simply Pythonize something.  
(Sounds like "Cometize it!" (tm))  That might even give it more
standard APIs for things than Java has.  Of course, then they
would turn around and call that a bad thing...

To be fair, not quite the same.  Java is a better fit for really tightly
constrained embedded systems.  We're not going to see Python running
on Smartcards very soon, at least not with the existing micros.  Nor,
perhaps, would we want to.  Leave Java the embedded niche, and Python
can continue to succeed in a niche where Java fails miserably: 
application scripting.

And the commercial telecom alarm monitoring system made by my employer.  
And our embedded controller module which runs Python... hmmm, I guess
Python can be effective in the right embedded application, too. :)
