So, all I need is comments from a computer scientist or two,
pointing out problems with the procedural/imperative programming
model, and we can establish that it was already hated and on its
way out by the late 90's?  How about OOP?  Already on its way out
by the time Python 1.0 hit the streets?

The thing that allows us to be so smug about the follies of the
past, is that we can pretend everyone knew better.
