Welcome to a new episode of The Flambda2 Snippets! The F2S blog posts aim at gradually introducing the world to the inner-workings of a complex piece of software engineering: The Flambda2 Optimising Compiler for OCaml, a technical marvel born from a 10 year-long effort in Research & Development and ...
A well-designed interface offers lots of expressiveness with minimal implementation. OCaml programmers thus often implement just a few functions in an interface (module type), then use a functor to define the rest based on these definitions. This idiom, though useful, can be awkward, requiring a little repetition. To make this easier, Jane Street designed the "include functor" syntax. This video shows how it works and why you might want to use it.
