I agree, however let us not get side tracked

Asking for pattern matching? it's not new feature, it's improving 
``switch``

Asking for tagged union? it's not new feature, it's improving 
``enum``

However, you are wrong at expecting an impact for D by improving 
OOP, nope, D needs to improve the non-OOP story, more OOP is 
repulsive, specially for system languages
