- This commit updates the formatting so that devs with the latest stable don't
see random format-fixes upon running `cargo fmt`

of a tuple instead. This has the nice benefit of printing inherited vars
in sorted order.
This adopts the new function store, replacing the C++ version.
It also reimplements builtin_function in Rust, as these was too coupled to
the function store to handle in a separate commit.
