I like the concept of interface, It enforces its successors to
implement some necessary methods.
Please take a look at the following example:
device.d
-
interface device
{
// I want the three methods implemented by its successors
void PowerOn();
void Powe

if D would allow this - what is then the difference between a
class with your methods as virtuals + your string?
interface are for loosier coupling then classes - thats why
only declerations not implementations (like your string) are
allowed, same goes to Java and C# (and i think most other

let me explain, abstract class requires its successors to
implement all methods, but may have fields.
class successors *always* do something, either their methods
has derived behavior or overridden ones. so does interface, if
you has class derived from interface then its successors ma

As mentioned by evilrat earlier the 'string signature' should
probably be made a readonly property, set in the constructor. I
don't think D supports defining a constructor signature on
interfaces (I could be wrong), so you want to define an
invariant as part of the contract.
