Every feature in a programming language has to be evaluated in a large 
context. There are lot's of useful features that OCaml doesn't have. Would
you add them all? 

I never said polymorphic recursion was useless, and I'd like direct support
for it added, so your claim that my analysis suggests it's uselessness
indicates that I am communicating very badly. I'll just be quiet on this

Actually, Jacques Garrigue's trick

but I just noticed that OCaml 3.05 has the same first class polymorphism on 
records and since there was no use of class features like dynamic binding
that a record dictionary is even better. 

BTW, the Caml mailing list archive is a really great resource.
