Decomposing datatypes into functors

14 min • 3 juli 2021

This episode continues the discussion of Swierstra's paper "Datatypes à la Carte", explaining how we can decompose a datatype into the application of a fixed-point type constructor and then a functor.  The functor itself can be assembled from other functors for pieces of the datatype.  This makes modular datatypes possible.
