Given a struct S with state and methods, Class!S should be a type that:
* is a class type
* contains exactly one member, having type S
* has constructors that forward to S's constructors
* has the same methods as S, with implementations that forward to the member's
methods
This offers an immediate means to convert a struct into a class that has the
same functionality but typical class semantics (heap allocation, reference
semantics, overridable methods etc).
Further ideas:
* define a clone() method that duplicates the state by copying the S member
* allow S to be a primitive type
* offer flags such as "all methods should be overridable" or "all methods
should be final", i.e. Class!(S, ClassOptions.allOverridable) vs. Class!(S,
ClassOptions.allFinal).
