Explicit is good, but D's problem is that it already have 
numerous language concepts covering the same type of semantics: 
classes, interfaces, alias this, template duck-typing, template 
constraints…

C++ only have classes and template SFINAE duck-typing. Everything 
else is just idioms or library constructs.

Adding yet another langauge level interface mechanism to D would 
IMO require language redesign. Which is not a bad idea, but not 
likely in the near term?
