Samppi,
Here's a parser-m monad I did.
(defmonad parser-m
[m-result (fn [x]
(fn [strn]
(list x strn)))
m-bind (fn [parser func]
(fn [strn]
(let [result (parser strn)]
(when (not= nil result)
((func (first result)) (second
result))))))
m-zero (fn [strn]
nil)
m-plus (fn [& parsers]
(fn [strn]
(first
(drop-while nil?
(map #(% strn)
parsers)))))])
I explain it in:

What kind of parsing are you doing?
Jim
