Er... almost every language uses whitespace as syntax, usually for token
delimitation (is that the word?). I believe that Fortran didn't use
whitespace as syntax. Ick.
Oh oh oh. You mean use whitespace as *block* delimiters. Yes, Python and
several other languages use that to some degree, Python rather deeply
So you should point out to those developers that it's *not at all* like
Fortran, and they should take a look and maybe a touch before tossing

Sure. Of course, there was no compiler based mechanism enforcing
consistent levels of indentation, was there? That *might* make a
I think, notwithstanding your experience with C (though why that should
be applicable to Python...), *you* have a riddle to answer: There is a
*lot* of Python code out there. The standard distribution contains loads
of modules from many different sources. You *yourself* indicate that
Python is becoming common place....
....*if* keeping Python block structure working were such a difficulty,
don't you think someone might have noticed by now? Given that it's
pretty much only a problem in a few, well defined places, why are you so
worried aobut it?

Not if the curly brace eating nano-virus strikes!

Er...not your experience of *Python* code, right? So, your experience
with Python code: 0. Everyone elses: >0 (some up to, what, 8 years? 10
years?). I think it more correct that your *lack* of (relevant)
experience leads you to your belief.
