synopsis: "Implementation and verification of an erasure procedure for Coq"
description: """
MetaCoq is a meta-programming framework for Coq.
The Erasure module provides a complete specification of Coq's so-called
\"extraction\" procedure, starting from the PCUIC calculus and targeting
untyped call-by-value lambda-calculus.
The `erasure` function translates types and proofs in well-typed terms
into a dummy `tBox` constructor, following closely P. Letouzey's PhD
thesis.

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-metacoq-erasure.1.0~alpha2+8.10 coq.8.11.2
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.11.2).
The following dependencies couldn't be met:
  - coq-metacoq-erasure -> coq-metacoq-pcuic = 1.0~alpha2+8.10 -> coq < 8.11~ -> ocaml < 4.06.0
      base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
  - No available version of coq satisfies the constraints
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-metacoq-erasure.1.0~alpha2+8.10
