    The documentation for Pkl.i3 says ``procedures are preserved.''
    Is this true for different programs containing some of the same
    modules, or true only for different invocations of the same program?
    If true for different programs, how is it done?

When Pkl.Write encounters a procedure, it writes the procedure's
qualified name and signature into the pickle.  The program reading
the pickle must contain a procedure with the same qualified name and
signature, or else Pkl.Read will raise an exception.  Different programs
reading the pickle could have different compiled code for the procedure.
Methods are treated the same way.
