I know this has probably been asked for a hundred times before, but I don't understand why D doesn't support this. Template alias parameters can accept nearly anything as an argument that standard aliases don't. I think standard aliases should be equally as powerful as their template counterpar

I had tried to start using D a while back and did some performance comparisons with Visual C++. D's back end doesn't seem to optimize very well when I tested it. I had a huge performance delta. How hard would it be to make the D compiler emit C code that could be compiled by another C compiler

Voldemort command structures

Voldemort types (coined by Andrei Alexandrescu) are types, which can't be named. Like so: auto getMisteriousData(int i) { struct Mysterious { int i; } return Mysterious(i); } The only way to use mysterious structure is to either do this: auto m = getMysteriousData(12);
