This is a good point about why OCaml’s stdlib is the right place for a Dynarray. When this topic occurred earlier, [Adding Dynamic Arrays / Vectors to StdLib](https://discuss.ocaml.org/t/adding-dynamic-arrays-vectors-to-stdlib/4697), @gasche commented on the preliminary steps to be taken near the end of that thread; the first steps being to enumerate the prior art and compare them. I looked for such a survey and didn’t find any. Is there such a thing? If not, where should it, reside? Perhaps in the underused RFC dir [RFCs/rfcs at master · ocaml/RFCs · GitHub](https://github.com/ocaml/RFCs/tree/master/rfcs)?
