Generic
strictly extends Generic_basic
.

Generic_basic
refers to the container type as 'a t
, and the element type as 'a elt
; substitute t
/elt
(arity-0) or 'a t
/'a
(arity-1) accordingly below.

filter c ~f
checks f
over every t
in c
, discarding any items for which f
returns false
.
exclude c ~f
checks f
over every t
in c
, discarding any items for which f
returns true
.
We can also derive Mappable
interfaces from filter-mappable ones, but leave that to a separate functor.
