exists `heap_lang.derived_laws`.
* Remove global `Open Scope Z_scope` from `heap_lang.lang`, and leave it up to
reverse dependencies if they want to `Open Scope Z_scope` or not.
* Add `min_nat`, a RA for natural numbers with `min` as the operation.
* Rename `mnat` to `max_nat` and "box" it by creating a separate type for it.
* Move the RAs for `nat` and `positive` and the `mnat` RA into a separate
module. They must now be imported from `From iris.algebra Require Import
numbers`.
The following `sed` script should perform most of the renaming (FIXME: incomplete)
(on macOS, replace `sed` by `gsed`, installed via e.g. `brew install gnu-sed`):
