It's true that not everybody understands what OOP is.

But I think everyone would agree, that data hiding is at the core.

First, I'm not advocating for OOP, or against it.

It's just a tool that's suitable in some scenarios, and not it 
others.

I'm also not a OOP purist.

Now with that out of the way....

D claims to support OOP. Put that to the test. Because there is a 
difference between programming with modules ('Decide which 
modules you want and partition the program so that data is hidden 
in modules.') and programming with 'user-defined types' ('Decide 
which types you want and provide a full set of operations for 
each type').

Data hiding is at the core of using modules.

It's also at the core of using types.

I refer interested people to:

"Most, but not all, modules are better expressed as user defined 
types." -
