I like the concept of interface, It enforces its successors to

Please take a look at the following example:
device.d

interface device
{
// I want the three methods implemented by its successors
void PowerOn();
void PowerOff();
void Reset();
string signature; // This is not allowed in D, but every
device should has a signature.
}
Why it doesn't support non-static members?
Actually in many cases, we need an interface which needs
enforce its successors to implement necessary methods,
meanwhile it needs has its own non-static members.
in this case you could switch to abstract class, or make
signature a read-only property
@property string signature();
