Three Unlikely Successful Features of D

[David]

I really love CTFE, even though it's sometimes pretty slow, maybe 
because I am axaggerating it …

One more thing are these slices, they really impressed me when working 
with pointers, float* v; v[x..y] = foo; ! awesome, no more memcpy

And of yourse opDispatch, I haven't used it a lot yet, just in gl3n for 
vector swizzling, I've seen glms swizzling ... I thought I can never do 
this in D, I made it in nearly no time and 10 lines of code!
