This is part of a set of commits that rearrange the dependencies between
multiple packages. The immediate motivation is to allow certain newtypes
to be reused between
profunctor
andbifunctors
, but this particularapproach goes a little beyond that in two ways: first, it attempts to
move data types (
either
,tuple
) toward the bottom of the dependencystack; and second, it tries to ensure no package comes between
functors
and the packages most closely related to it, in order to openthe possibility of merging those packages together (which may be
desirable if at some point in the future additional newtypes are added
which reveal new and exciting constraints on the module dependency
graph).
