- Developers seeking formally checked native code
- Worth noticing
- Its sample reports 12 of 12 checks proved across three subprograms: five statically and seven by the solver.
Field notes
The sample package defines `clamp` and `increment` with preconditions and postconditions, and appears as `.leon`, `.py`, and Ada source files. The page says `byronic run` proves and executes, while `byronic build` links a native executable. It also links to examples, explanatory material, and contact, and explicitly labels the project as under active development.
