[Kim Bruce]

Sounds good!

I'm trying to use exclusively Tim's editor at this point in order to further test everything for classes.  Let me know when these changes are available there.

Notably, Types now have a ‘methodNames’ method, which answers a set, you so can ask what methods are in a type.  Any object’s mirror also has a method methodNames, which also answers a set.  So, you can see why an object does not have a particular type.  For example:

> built-in lists are gone, which means that the list that you get back from various built-in methods should actually be real lists.   The variable arity parameter of a variable arity method is now a real sequence.   Done is the Top type, above Object.
