This series of blog post aims to give a short weekly glimpse into my (Florian Angeletti) work on the OCaml compiler. This week subject is the release of OCaml 5.1.1, some review work on occurrences analysis for OCaml projects and a bit of on-going work on structured logs.

Abstract module types are one of the less understood features of the OCaml module system. They have been one of the obstacles in the on-going effort to specify, and eventually redesign, the module system.

In this blog post, I (Clément Blaudeau) present an explanation of what are those abstract module types, and propose a slightly restricted version that might be easier to understand and specify while remaining pretty expressive.
