What is PL? I would appreciate more descriptive language.
I can see that Janestreet claim huge benefits from GADTs (check their blog).
I also came across a blog about writing GraphQL server using OCaml & GADT.
Worth checking out.
String/print formatting used to rely on unsafe Obj.magic. For a few years
OCaml string/print formatting is using GADT that provide compile time
safety. Lookup format6, and OCaml GADT for string/print formatting. That’s
the most real-world usage.
