description:
  The major use of @These@ of this is provided by the @align@ member of
  @Semialign@ class, representing a generalized notion of "zipping with padding"
  that combines structures without truncating to the size of the smaller input.
  .
  It turns out that @zip@ operation fits well the @Semialign@ class,
  forming lattice-like structure.
