Compile-Time Interfaces (Concepts)

["Nordlöw" via Digitalmars-d-learn]

AFAIK there is no compile-time variant of interfaces right?

Why is that?

Wouldn't it be nice to say something like

     struct SomeRange realize InputRange
     {
         /* implement members of InputRange */
     }

and then the compiler will statically check that that all members 
are implemented correctly.

I guess this requires some new syntax to describe what an 
InputRange is.

Kind of like C++ Concepts.
