module FieldMap : Map.S with type key = field_desc

Map indexed by both field types and names. This avoids name clashes between different sorts of fields such as values and types.

modtypes_constraint ~shape ~loc env ~mark exp_modtype constraint_modtype checks that exp_modtype is a subtype of constraint_modtype, and returns the module coercion and the shape of the constrained module.

It also marks as used paired items in positive position in exp_modtype, and also paired items in negative position in constraint_modtype.

This marking in negative position allows to raise an unused item warning whenever an item in a functor parameter in constraint_modtype does not exist in exp_modtypes. This behaviour differs from the one in check_implementation and compunit which assumes that is not appropriate to raise warning about the interface file while typechecking the implementation file.

check_modtype_inclusion ~loc env mty1 path1 mty2 checks that the functor application F(M) is well typed, where mty2 is the type of the argument of F and path1/mty1 is the path/unstrenghened type of M.
