I already gave my opinions on that issue elsewhere. First off, the
relative consistency in how Python uses blocks is a side-effect of an
unrelated principle, not a principle in itself - the 'right thing' can
still be to use block structure for other things. Secondly, Python
doesn't just use indented blocks purely to control program flow - it
is also used to define local contexts in the sense of local scopes
(class, def) so why not do the same, but with local options being the
local context?

Actually, I've been using Python for about 7 years or so, on and off -
slightly longer than I've been using C++, and it's almost certainly my
record holder for the longest period of sustained more-or-less-regular
use (though sadly not for quantity). I first started with Python 1.4
on an iMac, as a result of a desperate search for languages I could
actually run on that thing.

To the extent that I'm still learning Python, I'll probably always
still be learning it ;-)
