 meta-programming is a wonderful thing. actually, several years ago, i wrote 
 a book about it (in the context of Prolog, see my homepage) covering 
 meta-interpreters and partial evaluation in particular....

 hmm. you mentioned here twice "args" and "body"; you should not use
 these for inherited methods, use instead "instargs" and "instbody".

 i am still confused. Are you trying to use the instprocs as templates
 for procs? if i paraphrase the example from the wiki, this would be

   Class C
   C instproc fooTemplate <argument> <body>

   C c1
   useTemplate c1 fooTemplate foo -msg1 Hi -msg2 bye

 where the object c1 has afterwards a proc foo, and fooTemplate could
 be a proc or an instproc.

 i do not think, that this is a good solution, but this is an example
 where i would like to ignore the differences between procs and instprocs.
 is this similar to what you are working on?
