We can define new types with `struct`, `class`, `union`, and `enum`. Structs and unions

are passed to functions by value (i.e. copied) and classes are passed by reference. Futhermore,

That's thanks to a D innovation know as Uniform Function Call Syntax (UFCS).

With UFCS, we can choose whether to write a function call as a method
