Proof principles for datatypes with iterated recursion,s. We study proof principles for such data types in the context of categorical logic, following and extending the approach of [14, 15]. The technical contribution of this paper involves a description of initial algebras and terminal coalgebras in total categories of fibrations for lifted “datafuncto

When Do Datatypes Commute?, paper we formulate precisely the polytypic programming problem of “commuting” two datatypes. The precise formulation involves a notion of higher order naturality. We demonstrate via a number of examples the relevance and interest of the problem, and we show that all “regular datatypes" (tree-like d

A calculus for collections and aggregates,emantic foundations of the calculus we introduce a new concept: monads enriched with algebraic structure. We model collection types through enriched monads and aggregate operations through enriched monad algebras. The calculus derives program equivalences that underlie a good number of the optimizat

First Interlude: A Contingent Irruptionssion is a careful and detailed analysis of two examples, which tries to outline how the new categorical insights could help in guiding the development of a unifying theory for relations between logical systems.
