There is currently no simple way to make a substring goal beyond
manipulating strings as sequences which is not ideal. The constraint

build things upon it reliably yet.
So project is your best option for now.

It is necessary - integer literals default to primitive long and I'm not
sure if = will inline if it doesn't have type information in scope. This

Interesting, but there is still going to be a performance issue for
the perhaps-common case of testing a non-seqable for seqability: in
that case, it will do the reflective check for isArray and it won't

Running a program like that with cake run is awful, use AOT:
(ns clj-play.mapper
(:use [clojure.java.io :only [reader]])
(:use [clojure.string :only [split]])
(:gen-class))
(defn mapper [lines]
(doseq [line lines]
(doseq [word (split line #\s+)]
(println (str word \t1)

for 20 copies of the text so this looks like it's pretty much IO bound at
this point.

Hi,
I'm clear on what I want ;) (something new to me), but I'm not clear on how
to get there. I'd like to compare str1 and str2, if at least one of the

I haven't been exposed to logic programming besides the examples David
