Why are you using D instead of Rust?

I think I tried rust before I knew about D, but a the time, I 
wanted to define a mathematical vector type and couldn't do what 
I wanted because rust didn't have(but I think gained recently?) 
non type template parameters.  In D (and C++ which I was using at 
the time) it's easy:

`struct(size_t dim) Vec{  double[dim] data; ... }`

I did play around with rust for a bit anyway but found it too 
unfamiliar coming from C++, and then I found out about D
