If you get the git "wiki"[1] (open commit access) there are docstrings for many fns & macros, and the docs can be accessed from the repl using (help <name>), fns matching a prefix can be listed, e.g. (fns "m").
As a bonus, if you fire up (asv) and browse to http://localhost:8080/help there's some online help that links the bracketed "see also" [[names]] in the docstrings to their documentation.
