No, there isn’t. There were a few timid attempts in the past that went nowhere. In general, such initiatives are doomed to fail unless it is really somthing coming from the community and gathers sufficient backing there and among the main stakeholders (eg the maintainers of the “alternative standard libraries”). This is especially the case because the maintainers of ocaml/ocaml have around zero available bandwidth to dedicate to this issue.
In other words: if you or anyone else can bring such a thing into existence, that would be fantastic. But I expect such an endevour to be quite a bit of work, and involving a substantial “grassroots” component, and little in the way of support from the upstream maintainer team (especially at the beginning). But, again, if such a project got off the ground, that would be fantastic.
This committee is intended as collegial instance with the aim to facilitate discussions and consensus making about the evolution of the OCaml language and its standard library.
Windows permissions are defined by Access Control Lists. There are no simple user/group/other right templates. We can defined rights of single file to different groups or different user for exemple. And there are more right types (total control, modification, read, read&execute, write, special)… instead of just read-write-execute.
