MetaCoq/metacoq: MetaCoq 1.3.2 for Coq 8.20

Release 1.3.2 of the MetaCoq project for Coq 8.20 is available both as source and through opam. See the website for a detailed overview of the project, introductory material and related articles and presentations, and the release notes for 1.3.1 for a summary of the changes w.r.t. previous versions.

The main changes in this new version w.r.t. v1.3.1 are:

What's Changed

• Proof that reordering of constructors is correct by @mattam82 in https://github.com/MetaCoq/metacoq/pull/1095 This allows in particular to switch the representation of Coq booleans so that extracted code matches the ocaml representation of booleans, making interoperability with existing OCaml code easier.

• Add the force (lazy t) evaluation rule to LambdaBox by @mattam82 in https://github.com/MetaCoq/metacoq/pull/1089 We verify that the evaluation rule is preserved by the verified transformations. In particular, this allows the coq-verified-extraction package and certicoq to support coinductive types and cofixpoints by interpreting lazy/force. The verification of the translation from cofixpoints to fixpoints + lazy/force is however still a work in progress.
