 i have no idea why you call this a stupid feature - IMO this all makes
 the program shorter and as such more readable. this is really something i
 hate about python, missing ++ and -- operators plus having to do the
 assignment stupidly before if comment - more & longer source.

   :) maybe C++ programmers like you? i personally never had any problem
 with ==, && and ||, what's more - in the source those 'glyphs' help to
 increase the readability - there's less of real text. can you describe
 your problems with those operators? oh, and don't forget C/C++ has been
 here for years - it's like with VI - you hate it until you
 get to know it in deep.
   and one more thing - most programming languages are similar to C/C++ in
 syntax - and most programmers are/were coming from C/C++ world. making
 differences like and, or instead of && ||, or no assignments in if
 statements means much less people actually like python and refuse to use
 it. it has some really great features, other are really stupid and
 uncalled-for.
