How do you manage to change a pass-by-value to pass-by-reference by 
changing an alias?

e.g.

struct Vec3(T) { ... }

T dot(Vec3!T a, Vec3!T b)
{
   return a.x * b.x + a.y * b.y + a.z * b.z;
}

/* lots more functions that pass Vec3 by value */


How would you change Vec3!T to be passed by reference by changing an 
alias param?


P.S.
In C++, you'd change

T dot(Vec3<T> a, Vec<T> b)

to

T dot(Vec3<T> const& a, Vec3<T> const& b)

No need to change . to ->
