  • Profunctor optics are bidirectional data accessors that capture data transformation patterns such as accessing subfields or iterating over containers. They are modular, meaning that we can construct accessors for complex structures by combining simpler ones. Profunctor optics have been studied only using $\mathbf{Sets}$ as the enriching category and in the non-mixed case. However, functional programming languages are arguably better described by enriched categories and we have found that some… CONTINUE READING
