I second for Neil. If my Scheme has the same operation as the SRFI's with a different name, it is trivial for me to support the SRFI by adding one line of definition. I expect supporting any SRFI requires some amount of work anyway (at least I need to add a documentation to mention the SRFI support), so I don't see a compatibility problem in such a case. In this particular SRFI, I'm for -ref, -set! and -delete! for consistency of R5RS and SRFI-1/13 operations. The real compatibility problem arises when the same name is used for different API or semantics. In this particular srfi, I see a couple of such conflics. - The 'default' argument handling of hash-table-get conflicts with PLT's hash-table-get, which requires a thunk. On the other hand, the current proposed API is consistent with STklos, Gauche, and Chicken at least. - make-hash-table has wider variations among implementations. Most implemtations seem to be able to support the current proposed API by dispatching with the type of the first argument, but ironically, the STklos's make-hash-table, which has the most similar API to the proposed API, conflicts, since STklos's hash function doesn't take optional 'bound' argument. It may not be easy to design a hash table API that avoids any conflicts with the existing implementations; should we invent a new name other than hash-table-* ? --shiro From: "Neil W.
