OCaml 4.11.0, first alpha release

The set of new features for the future version 4.11.0 of OCaml has been frozen.
In the next few months, the OCaml compiler team is focusing on bug hunting and fixing.

For this release cycle, we have decided to test publishing regularly alpha versions of OCaml 4.11.0 in order to help fellow hackers join us early in our bug hunting and opam ecosystem fixing fun.
Once the opam ecosystem is in shape, these alpha releases will morph into the usual beta and release candidate releases.

If you find any bugs, please report them here:

The compiler can be installed as an OPAM switch with one of the following commands

opam switch create ocaml-variants.4.11.0+alpha1 --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git


opam switch create ocaml-variants.4.11.0+alpha1+VARIANT --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git

where you replace VARIANT with one of these: afl, flambda, fp, fp+flambda

The source code for the alpha is also available at these addresses:
