Thank you all for your excellent comments.
I was aware of Hughe's technique and the 'whyfp' paper.
I had often thought that some kind of iteration would be necessary to reolve
this, and to overcome initially this I was cheating and using one of the
values one step late in order to break the closed cycle of references, in my
C and Prolog protype versions.
This cheat bothered me to the extent that I decided to fix it and that is
when I decided that I might be missing the boat, and Haskell might have a
built in solution to closed sets of references.
But I see now in retrospect that this was a misguided (could I say silly ?
;-) notion and that indeed some kind of numerical algorithm will have to
be effected to get the 'pure' solution.
Again, many thanks to all, and I learned something valuable.
My faith in Haskell and FP has been restored (assuming it ever did actually
