  I've added a third post: [https://diskuv.com/mlfront/overview-3/]

  In it I describe a small but useful /reference build system/ for
  MlFront which can take packages like:

  ┌────
  │ .
  │ ├── AcmeWidgets_Std/
  │ │   └── A.ml
  │ └── BobBuilder_Std/
  │     └── B.ml
  └────

  and produce standalone build scripts that can be committed to source
  control:

  ┌────
  │ $ mlfront-boot -native -o buildscript
  │ 
  │ $ ./buildscript.sh # .\buildscript.cmd is also created
  │ 
  │ $ target/BobBuilder_Std.B
  │ I am an A!
  │ I am a B!
  └────

  On a related note, I've begun to implement a small part of
  <https://gallium.inria.fr/~scherer/namespaces/spec.pdf>. It is not
  strictly required but [Namespaces.mli] will be very helpful for
  upgrading existing projects to `MlFront'-style packages without
  changing code. That will be for a future (not soon) post.

First release of hector

François Pottier announced

  It is my pleasure to announce the first release of `hector', an OCaml
  library that offers /vectors/ (also known as dynamic arrays, or
  resizeable arrays).

  To install it, type `opam update && opam install hector'.

  `hector' offers *polymorphic vectors*, where the type of the elements
  is a parameter, *monomorphic vectors*, where the type of the elements
  is fixed, and *integer vectors*, a special case of monomorphic
  vectors.

  `hector''s vectors are *not thread-safe* and *do not include a
  protection against memory leaks*. Compared with the `Dynarray' module
  in OCaml's standard library, `hector''s polymorphic and monomorphic
  vectors are *slightly faster*, and `hector''s integer vectors are
  *significantly faster*. `hector' offers fast (but dangerous) *unsafe
  access operations*, namely `unsafe_get', `unsafe_set', and
  `unsafe_borrow'. For a more detailed overview, see the
  [documentation].
