//! Options contains everything related to engine options. The idea behind this is to take as much
//! advantage of the typechecker as possible. As a result, engine option names are constant static strings,
//! and EngineOption tries to be flexible so it can be reused for each option, which also maintaining some
//! of the nicer parts of typechecking.
