Hi Scott,

i am not exactly sure, what you have in mind with your example.
However, a forwarder in xotcl is a c-implemented method. Therefore it can
be deleted like every other method by

   <obj> proc <method> {} {}
   <class> instproc <method> {} {}

below is a simple example derived from yours...

Object a
a proc foo {args} {

}

Class C
C instproc foo args {
  puts "[self] default foo"
}

C b
b foo
puts "start forwarding to a"
b forward foo a %proc

b foo
puts "stop forwarding to a"
b proc foo {} {}
b foo
