Hi all, Unrelated to everything, a comment about Python 3's unrivalled syntax. You can now be hesitant in your programs! Try it out: if len(x) > 0 and... and... and x[0] == 5: More seriously, I'm used to type "..." somewhere to mean "fix me first!". I didn't move to Python 3 so far, but if I had to pick a reason, this one would be high on the list. Now the program will associate a useless meaning to my "..." and try to execute it. Even worse, in the usual case (a line containing only "...") it will work: the line is completely ignored! You can write this: def foo(): x = ... ... and actually execute foo() without getting any error. Likely you'll end with a crash later because this call to foo() didn't have the expected effect, which you did not implement so far. Same with "assert...", which just passes. Great! I guess I just have to remember: use 4 dots, never 3. </rant> Armin
