Document and adjust `hash-clear!', `hash-clear', and `hash-empty?'. Also, add `hash-copy-clear'. The clear operations are constant-time for a non-impersonated hash table, otherwise they always remove keys one-by-one to trigger the impersonator's interpositions. The `hash-clear' operation works only on immutable hash tables, in contrast to the original implementation. The new `hash-copy-clear' works on both immutable and mutable hash tables. The "copy" in its name is meant to suggest a difference with `hash-clear', even on immutable hash tables: any chaperone on the input is not on the outpue. Change `set-clear' to be like `hash-clear', and add `set-copy-clear'. (Changes are in consultation with Carl.) |
