I switched my personal game to D from C++. Was easy, most of it 
was just copy paste. I was writing a math library to replace the 
one I was using to make it a bit more light way and to fit my 
needs a bit more. I didn't like how some thing were implemented 
in the library I was using. So I started with templates, I need 
multiple types and what not for the same purpose. At some point I 
have a function that needs to take 2 different template types.
It starts to get so convoluted, order matters cause C++ still 
just uses copy-paste-includes and I don't think modules made it 
into C++17. I wrote the same library in half the code, in a way 
that's more readable and manageable. I didn't have to define 
things so that they would work, I could define them logically the 
way I'd expect them to be. Mixins also reduced code quite a bit, 
generating functions for different types and dimensions. Even 
though you have constexpr if statements now you still need to 
define all the function bodies even if they all can go in one 
function body now.
