I am sorry to say that I find your exposition extremely confused, but this one at least has a simple answer. There is no standard way to remove special proclamations, but they are associated with a symbol, and there are at least two ways to get rid of symbols. The function `uninternĀ“ ensures that the name of the symbol will no longer map to the symbol that has the special proclamations associated with it. The function `delete-packageĀ“ ensures that you can no longer access the package by name, and unless you have the package as your current package, you should be able to start afresh. A simple way to ensure that you start off fresh with an experiment (although I think experimentation to discover how special variables works must fail), is to create a new package for each run of your experiment and discard it when you are done. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
