I want to to some vector maths. I'm trying to figure out the
best way to make my own class for it. My first thought is just to
extend Array? But then I think, well they have some things in
common, but I doubt I will need to sortOn() a Vector, or splice().
So then I think maybe composition is a better way to go.
And then I've also got the problem that if you have an array
of length 5 and you do this:
Flash has no problem assigning a value to element 100!
I was thinking of first doing this in AS2, because I know
that better and probably eventually migrating it too AS3. Some of
these vectors will be pretty large (65536 elements long) so I do
need to try and keep this fast.
