   IMO, a single Vector implementation is not PAYG.  If I just need one 4 element Vector<uint>, how much code is that going to cost me?
   
   Ideally, the compiler would output the correct set of information the implementation needs, and different implementations could optimize as needed.  I think that's how E4X is proposed in the ECMA spec and implemented in Royale.  Various E4X syntax in AS ends up as low-level calls to the E4X implementation.  I am hoping we can do something similar for Vector.
   
   Some Vector implementation like the one you are working on can be the default, but there should be a way to get cheaper implementations if you need them.
