Well, honestly, this is really what I understood when I've read:
"the compiler can detect a lot of errors and save you from having to
painstakingly & laboriously test every little detail. For a large
program or system that really cuts down on the work (and hence time)
and really increases quality"
which what you did write, right?

So maybe it is an understanding problem on my side, but even if it is,
other people may have the same as I had, don't you think?

Well, I won't go into how C++ code tends to be quite longer than their
Python equivalent (maybe I'm not too good at flame wars after
all... ;-) ). But the application I'm working on right now includes
nearly 300000 lines of Python (among other languages). That's not a
million indeed, but I wouldn't call it a small application. I've done
a lot of C, Java, and some C++ as well before. And so far, what I'm
seeing is that if you organize your work properly (TDD mainly...), the
development goes faster, with no significant decrease in quality for
the final product. So yes: I would consider a million line Python
system without fear.
