Is there maybe a way to implement commonly needed vector classes Vec2, Vec3, Vec4 without having to implement the same basic code over and over again?

I have implemented a generic nD vector struct for D1. When I have translated it to D2 I can show it and Andrei may add it to Phobos, because everyone and their uncle need vectors.

There are several ways to implement a generic nD vector, the size is a template argument, and templates or CTFT + string mixin allow you to perform the operations with no loops in the final code.

The following are a few libraries that have already implemented vector classes/structs for Vec2 .. Vec4, they might give you some ideas should you decide to roll your own :)

Have you done so yet?
