IO requires Bimap #46

Closed emilypi closed 6 years ago

emilypi commented 6 years ago

We currently do not have a bimap for IO. As a bifunctor this is necessary for calling it a bifunctor. If someone wants to implement the new tag and case of the IO runtime supporting it (for instance, as was done with the Map and FlatMap tags), that would be greatly appreciated.
