yes, but it doesn't say much on the history of the problem. The Paulson
book does, but doesn't mention Caml. What I wonder is when Caml
adopted value polymorphism, what system was used before that and whether
the INRIA researchers did seek for (perhaps alternative) solutions
themselves. In the Standard ML community, the standard reference to this
problem is a paper of Andrew Wright (1995)...
