[Pharo-project] Complete MethodContext stack for testing

Hi guys. We need to do some test to serialize a MethodContext to a file, materialize it, and then compare it to the original. One of the problems we face is that some values in the MethodContext are changed so it is difficult to test. So...what we would like is to get a "bottom" MethodContext that we can ask #sender, and to that one #sender, and like that....and the whole stack should cannot be changed. Another problem is that I cannot do a #deepCopy on a MethodContext because #basicNew: throws errror. Is this possible? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
