Pretty neat, Hawke.
I didnt mess with the angle, cuz I was wondering how I would do that for
multiple dimensions.
However you can easily calculate distance of two points defined in 5
dimensions.
And in one, is no problem also. Its just pos (a -b)

Could we get angles to work in any number of dimensions.
In theory, giving 2 dimensions, you will get {distance, angle}
Giving 3 dimensions should give you {distanze, xyangle, zangle }
And with 4 dimensions we should get {distanze, xyangle, zangle, more_angles}

And Hawke, I started to talk about sum ()
Lets try an optimization thread on sum ()
Here is the beginning function:

function sum (object x)
atom ret
    if atom(x)
        return x
    elsis not length(x) then
        return 0
    end if

    ret = sum (x[1])
    for index = 2 to length(x) do
        ret = ret + sum(x[index])
    end for

    return ret
end function

Oh yes, Hawke, I forgot all about that. You're right, I should have used the
a * a approuch.
Oh well, I think it will be the fastest.
The sum function above on the otherhand is just a simple one, it can be much
faster I think.
