No. Here's where I must disagree. I think one can infer a goal for particular programming languages, even if it is subconscious. For example, with LISP it could be "generality". For C, it could be "staying as close to the machine as possible while maximizing the use to humans" -- contradiction that works because they've limited their architecture to VonNeumann (stackless) machines. I think the subconscious goal of OOP languages is to create a data ecosystem, starting with a unified data model under the realization that ultimately: all data relates to other data -- that my database of wind speed and direction from 2012 is relatable, by some finite number of hops, to your data on population growth in Chicago. Call it the "seven degrees of data" and remember the exabytes of data out there. Python is creating the perfect system for that because it has an interpreter environment with which to manipulate objects that could be retrieved on the net and sent back out. It has docstrings so that your foreign object can self-document, and doctests, so that I can be confident that your code works as *I* expect. There are reasons to have limits on programming freedom. It puts order to chaos. It guides the wily programmers into a particular train of thought. You don't override "True" because you'd be breaking one of the [explicit] goals of the language: readability. If there were no constraints, life itself could not exist. I don't think shadowing built-in types was a design choice but simply never got exercised because most people are used to handling such things, *subconsciously*, like C. To Mr. Gatti, my point was not an insult, it is a theoretical postulate in the domain of Computer Science. One that has not really been studied. OOP is still far from it's goal, so the field is still answering questions within it. Mark -- https://mail.python.org/mailman/listinfo/python-list
