Hi

One of my projects asks for a type constraint in multi-argument functor as
follows:

Module Make (A: BLA) (B: BLA with type t = {a:A.x;b:A.y}) = struct ... end

In other words, I want to constrain t to be a record type with types as
defined in A (and declared abstract in the signature BLA). Unfortunately,
the obvious way above does not seem to work. Can anyone tell me how to do
this ?

Please also cc me in your response to the list.

Cheers
