You could enable this easily using a wrapping struct template. 
Have a look at this: https://run.dlang.io/is/6CNgpy

In short, the solution is very elegant, very general, and only 
requires you to make two keystrokes `.v` before the operation. 
Alternatively, you can use `v(1, 2, 3)` instead of a slice 
literal.
