# To do
- Many more tests and examples.
- Improve build process:
- Why can’t we make bindgen a Cargo dependency?
- Should we include a copy of libffi in the package?
- ClosureOnce!
- high::BuilderN?
- Do we need to use `std::thread::catch_panic` somewhere?
- Custom complex number types? But Rust doesn’t support complex numbers
anyway...
- CIF inspection?
