Ok I can see that. On that front, I'd like to point at this 
specific timestamp: https://youtu.be/raB_289NxBk?t=2775

This part IMO, point at what the #1 problem with the way things 
have been done in D. D's feature just don't compose well because 
they aren't orthogonal with each other (and many are 
inconsistent).

C++ used to be very much that way too, and but it is clear that 
this is something that has changed with C++11 onward.
