Each time you define a functor you also have to give the signature of
its argument, which, compared to a simple "include" can look overkilling.
Concretely:
module A = struct
...
end
module B = struct
include A
...
end
VS
module A = struct
...
end
module type B_INPUT = sig
... (can be big)
end
module Make_B (X:B_INPUT) = struct
...
end
This verbosity problem is actually less true since 3.12 with the
introduction of "module type of":
module A = struct
...
end
module Make_B (X: module type of A) = struct
...
end
Which is then quite close to the "include" version.
