control yourself. Why should you want to type that? It's not necessary
in Python's loops which automatically increment for you.

"Incremental operators" arrived in Python 2.0. They weren't "left out"
before just not implemented. Features should only be added to a language
when a real case for them can be made and the PEPs now give a valuable
insight into this process in Python. I like Python because when I read
the discussions I understand why things are or are not there. Check
which version of Python you've got and upgrade if necessary. Python 2.0
and Python 2.1 include a whole set of improvements see Andrew Kuchling's
readme's on the website.
