One note about point (2) dealing with the versions and the languages object oriented features. I noticed the object-oriented support has been tacked on, before Python 2.2 the objects had their own type which was accessed by .__class__. The tacked on nature of the OOP support of the language is perhaps why there are these __identifiers__ which are hard to type using consecutive letters, needing shift to be held down, are still used in the language. Although Python fixed the problem partially, it only did so only by adding new style classes along the old style ones in order to avoid breaking compatibility, which only complicated the issue. Unfortunately, Python 2.7 is still around. As this post mentions, Python 2.7 & 3 are both installed on Linux machines and the default is still Python 2.7 when you type python.
