Yes, but its not that hard. They can integrate with Tiny-CLOS if the SRFI-44 implementation they're using isn't using a more native feature of the Scheme system, or that system otherwise. Adding the collection to whatever dispatch mechanism is being used is pretty trivial compared to actually implementing the collection. > >> Between R5RS, SRFI-1, SRFI-13, and a little glue code, a programmer > >> can actually do *better* than he can with SRFI-44. > > > Yes, but not for future collections. > > SRFI-44 doesn't let him do better for future collections, because it > doesn't specify how to add new collections to the existing set. And it can't until a dispatch mechanism is standardized and everywhere, but its not as bad as you make it sound. Scott
