The last seemingly incomplete part of the spec seems to be the Dictionary type, which specifies m:n mappings. While the interface currently specified by the SRFI would work, it has a couple of weaknesses: * It doesn't distinguish between dicts where values mapped by a key must be unique (ie a dict-set) or not (dict-bag). * Few people I've spoken to (including myself) know what actually makes a good interface for such dictionaries. The former point argues somewhat to *three* map types, and both say to me that more work (possibly a lot more) would be required for an interface that is worthy of being called Schemely. However, I'm of the opinion that the m:1 Maps currently defined are pretty non-controversial and elegant, so I'm considering dropping Dictionaries from this SRFI, but having a fairly strongly worded future work statement in the SRFI about them, and also archiving the current API on this list. This would leave SRFI-44 very usable for 99% of people (who really just want a hashtable), but not accidentally standardize an M:N interface which frankly needs more expertise than is currently assembled.
