Raw string manipulation in D's mixins is much more limited than in CPP, and it's also not the only tool available for metaprogramming. https://dlang.org/mixin.

I'm sorry to not bring examples, but if you look for them yourself, I think you'll find that D's metaprogramming looks nicer than C++'s constexpr.
