You don't need to use 'ref' on parameters that are classes. Unlike C++,
D classes are already reference types, not value types. More like Java.
Structs, OTOH, are value types. With t

Yeah, true in general, though it is possible to have a struct be
very similar to a reference type. Consider:
struct WrappedClass {
Object obj;

opEquals doesn't work on classes with class references. It
doesn't call a method with obj = other_obj, it just rebinds the
reference. If you want full control over opEquals, it'll have
