Lack of bullshit in the source file.

Unlike some D programmers I don't mind rust but compared to C and C++ the primary difference I'd say is that D has a lot of features that you'd have to emulate with either macros or recursive templates that means that the source files end up much cleaner.

If you want to declare a struct with N members where N is declared at compile time, in C++ it's usually a question of doing a bunch of compile time magic that leaves a roadside picnic of SFINAE everywhere whereas in D it's just a "static foreach" loop inside a template.
