Functor
A version of btmap specialized to a single argument.
Traversable
A traversable bifunctor is simultaneously a TraversableT and a TraversableB.
Traverse over both arguments, first over f, then over g..
A version of bttraverse specialized to a single argument.
bttraverse1 with the arguments flipped.
Map each element to an action, evaluate these actions from left to right and ignore the results.
Map each element to a monoid, and combine the results.
Applicative
If t is an ApplicativeT, the type of tpure shows that its
second argument must be a phantom-type, so there are really no
interesting types that are both ApplicativeT and ApplicativeB.
However, we can sometimes reconstruct a bi-applicative from an
ApplicativeB and a FunctorT.
Conceptually, this is like simultaneously using bpure and tpure.
A version of btpure specialized to a single argument.
Simultaneous product on both arguments.
