- Sounds nice -- but can it be done efficiently (both in space and speed
- of method dispatch)? Anyone know of any successful examples?

- How about the MEROON package which is available for certain Scheme
- systems (it doesn't use the new macro system :-( It is a sort of
- mini-CLOS system and if I remember correctly, the documentation states
- that the amortized time for a "method" call is 2.5 normal function
- calls. Whether this is "quick enough" I can't say, you'd have to try
- it and see. You can find MEROON in the Scheme Repository :-
