That would be really nice. subr-x contains some extra hash-tables
functions already and I'm wondering how it should be dealt with without
implementing some functions twice if we were implementing a map.el
library. Should we keep hash-table functions in subr-x and simply alias
them in map.el or remove them from subr-x.el?
