Bug in clojure.algo.monads prevents you from using :require :as ns declaration

[Rick Moynihan]

Hi all,

I think I've found a minor bug in clojure.algo.monads.

If you do the following:

(ns foo.bar

  (:require [clojure.algo.monads :as mon]))

You cannot use mon/m-lift (and possibly others) as m-lift expands like so:

user> (macroexpand '(mon/m-lift 1 prn))
(fn* ([mv_4553] (m-bind mv_4553 (fn [x_4554] (m-result (prn x_4554))))))

Note that m-bind is not fully qualified which results in errors like this:

CompilerException java.lang.RuntimeException: Unable to resolve symbol: m-bind in this context, compiling:(/private/var/folders/6j/vpfh3hk97mq82r9nmq7d2h0h0000gn/T/form-init2703504198066353121.clj:1:1)

The github page for clojure.algo.monads does not mention how to post bug requests.  I'm assuming as it's a contrib project it's done through Clojure's JIRA.

Can anyone offer some guidance?

Thanks.

R.

Hi Rick

As far as I know, m-lift and similar functions should be used in monad context (using with-monad macro).

Greetings.
