Pros: The ALU of any computer uses boolean gates to build an

bools to be (strings of) bits seems natural

I am trying to use PyRTF.
I gather that an RTF doc consists of a list of sections, a section
consists of a list of paras,
paras seem to be just text (not sure on that one)
Some questions:
When does one end one section and start another?
How does one handle lists (as in numbered, bulleted etc)?
-
The real issue is not tabs/spaces vs braces but academic/scientific
orientation vs engineering/commercial needs.
Mostly these worlds are so far separated that no dialogue happens --
think C vs Pascal, Java vs Eiffel etc
The problem -- actually advantage -- is that Python straddles both worlds.
