[mercury-users] Okay to add permutation to typeclassed RNG protocol?

[doug.auclair at logicaltypes.com]

Dear all,

I have a need for a random permutation of a list, and it appears that
the implementation in the standard library does the job.  Can it (modified 
with typeclass constrants instead of random.supply values) be appended
to the protocol Julian has put forward for the proposed RNG typeclassed
protocol?

Thanks.
