// WHAT IS THIS?
// This is me playing around with a cool (but dirty) trick
// Some interfaces can be globally augmented to provide info to the type system
// This then allows some basic type switch and retrieval operations
// I needed a DeepReadonly<T> for a thing, I think I have it now
// Built/tested in 2.5.0-dev20170803

// FUTURE PLANS
// - This needs lots of tidying and renaming
// - Do more stuff
