Hello.

I am unsure if I am going about this the right way, and if my question even makes sense.

In essence what I want is to have two "types" represented by a size_t. Here is an example of what I want think I want (but might be completely off)

    alias Foo = size_t;
    alias Bar = size_t;

    Foo foo = 4;
    Bar bar = foo; // i want some error like
                   // "cannot implicitly convert from type Foo to Bar"

My best solution is to have the types as classes to force type checking.

Is there a better way to do what I want here?
