Re: Removing things from Context

Mike, 

I notice that you authored Avalon's OverridableContext which sort of solves this
problem.  However I can't cast down to it.  My solution at the moment is to do
what you do in this class, basically when I want to "remove" something from
context i just do a hide on it.....
