That isn't my experience. In my work on DMDscript in D, I changed some 
types between struct and class to try out some variations, and found it 
to be a lot easier than in C++. For one thing, I didn't have to find and 
edit all the -> and .'s.

But you're right that C++ allows you more choice - you can create a 
polymorphic type with value semantics. I think D is better off without 
them, however.
