For reference, Wikipedia offers "accumulate", "compress", "inject", and "foldr"/"fold-right" as common synonyms for reduce. Similarly "collect" and "transform" for map. Perhaps these words should appear in the docstrings just for searching purposes? > >> I've certainly asked my fair share of noob- >> questions, and folks in this group have been quite happy to oblige me. > > Yes; it seems the derision comes when you don't find something and > then instead of asking after it here you actually implement it > yourself. :) This is rather odd -- normally, self-help should be > rewarded in preference to always bugging the forum for assistance, not > punished.

This seems to assert *as fact* that it is missing, fails to acknowledge the possibility that (either by accident or by documentation that could be more comprehensive) you simply overlooked it, and perhaps worst of all, suggests incompetence on the developers' part for excluding it. There are many extremely smart people, far smarter than I am, working on Clojure and participating in this mailing list.
