It is not automatic at least because of implementation details: The 
compiler should not generate a vtbl for every possible interface.

Is it acceptable to add IAB and IBC to C? If so, this works:

import std.stdio;

class C : IA, IB, IC, IAB, IBC {
     void a() { writeln(__FUNCTION__); }
     void b() { writeln(__FUNCTION__); }
     void c() { writeln(__FUNCTION__); }
}
