I had a look at Loci, more specifically the language goals[1]:
"While technically useful, the C programming language is often perceived as lacking sufficiently powerful abstractions to construct large and complex systems. For this reason, languages such as C++, Objective C and D were invented to provide abstractions on top of the language.
Unfortunately, these languages have significant problems. For example, C++ and D place undue attention to compile-time functionality that serves to complicate the source code."
I wonder what they mean specifically. Looking at Loci code, I can see more or less the same ideas, and a syntax similar to C++ and D.
The author goes on to talk about C++'s complicated semantics, which is fair enough. But it gives readers the impression that D is more or less the same as C++ and thus has the same problems. I think it's not fair to lump C++ and D together in this way.
