In tree calculus, computations are given by natural trees, i.e. finitely-branching trees without labels. The functions, data structures, programs, inputs, outputs and values are all given by binary trees. The trees are built as combinations of a single operator. It has three evaluation rules, for leaves stems and forks. This is enough to support reflective programs such as a size function that can decide its own size, an equality program that can decide its own equality, and self-evaluators than can evaluate themselves. Since this does not require any meta-theory for, say, substitution, quotation, serialisation or Goedel numbers, it is simpler and more powerful than traditional models of computation. The organisation of the proofs is shown in the _CoqProject file, with one or two files per chapter.

Dry install with the current Coq version:
opam install -y --show-action coq-tree-calculus.1.0.0 coq.8.6.1
[NOTE] Package coq is already installed (current version is 8.6.1). The following dependencies couldn't be met: - coq-tree-calculus -> coq >= 8.12 -> ocaml >= 4.05.0 base of this switch (use `--unlock-base' to force) - coq-tree-calculus -> coq >= 8.12 -> coq-core -> ocaml >= 4.09.0 base of this switch (use `--unlock-base' to force) No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-tree-calculus.1.0.0
