Why is D unpopular?

Pattern is very close to how classes work in Simula, just 
generalized to cover functions and more. You can have executable 
code in the body of a Simula class too.

Lambdas in C++ captures some of that spirit.

What tends to confuse people is that they conflate OO with 
language features, but OO is a modelling strategy, not a language 
extension mechanism. OO language features are there to make 
implementation OO models easier.

OOP is a good features set to implement a model, but usually 
inadequate for extending the language (which is never was 
intended for).

(Regardless, D is class based and should be evaluated as such.)
