Matthijs: Progress on OCaml parser for Stan3.
Ben G: RStanArm is ready to go, waiting on RStan next release. Worked on how to do includes of Stan programs in Stan programs.
Charles: Found class of models where the quadratic analyzer does poorly. Interfering with a model that Shosh wanted to fit. Going to post to discourse. Thinks this because of sharp discontinuities. Working on McGill slides.
