I think I want something like this:

PROC Test (CHAN OF XX chanIn.a, CHAN OF GHOST <chanIn.g><server>)
  ALT
    chan.a ? input.a
      ... Process input.a
    <chanIn.g> -- This code is attached dynamically and
      -- exists in some other source file, and is sent by
      -- some run-time system when another process installs it.
      <server>
  
I would like to remove the code as well, and I would like to
control outputs the same way. Maybe this whole idea is stupid,
because we might get into all sorts of inheritance problems
and aliasing and you name it?
