MzScheme provides mutable hash tables keyed by symbols - actually, by any data - but I can't find any functional mappings, i.e. where insert and remove operations produce new mappings and preserve their inputs. I've had many occasions to want lookups based on symbols and it would be nice to have the option of persistent data. Is this present somewhere I've overlooked, or is this a feature that could be added? --Carl
