A generic equality should be one that work with recursives. A such
equality is slower than the Pervasives.(=) one. So (=) is just an
optimisation of a generic one that don't have been fully implemented.
When the compiler generate code he have the complete type, no ? so he
can know if a type is recursives or not, so he can select the slow but
recursives compliant version are the actual.
Maybe that it is more complex than this, no?
