Why do we need 3 Vector3 types?

[Shadowraix]

The three types are used in the C++ code, and it would be quite difficult to merge them on the Lua side, simply because any exported function that takes or returns a Vector3<T> would need to be exported manually.

So basically a merged Vector3 function isn't practical due to issues on the C++ side of things?

This kind of seems like a big issue if you can't control a separation between the C++ API and the Lua API
