[mercury-users] Request for comments on this code

[Nicolas Pelletier]

Hello,

the following code  solves the  N  queens problems using a  constraint
based approach. It  is a rather direct  port from a  Prolog program. I
wrote this program  as an exercise  in learning Mercury concepts,  and
would like other  mercury users to tell  me  what they think  could be
improved: is  the style right  ? is there  a better  strategy to write
this kind of algorithm ?

For the record, the attached code is  not blindingly fast, but it only
uses native Mercury constructs (as opposed to calling some optimized C
code through FFI).

Thank you in advance for your answers,
