Ok. Not hard. And not hard.

No, it doesn't. The use of 'larger' was just vague IMO.

You've made my points for me. =) (Tho I'd probably do the DBMS in C,
with a Python front-end and API hooks.)

True. Python's age and amount of support were not the point. The point
was that even C can implement large, scalable, OO-type ideas like

Maybe I was wrong in my inferrence, and this probably isn't the location
for personal opinions on corporate business practices. But no; the jab
just came to me while writing.

All very good points. I have certain reservations, tho. I dread
waiting for Microsoft Word to startup as it is, written in compiled C++.
I fear for the speed of anything of that scale and complexity
implemented in Python.
