Then don't just talk about it, raise a bug - otherwise how do you
expect it to get fixed!  ( http://www.gdcproject.org/bugzilla )

I've made a note of the error you get with `__vector(float[4]) c =
[1,2,3,4];' - That is because vector expressions implementation is
very basic at the moment.  Look forward to hear from all your
experiences so we can make vector support rock solid in GDC. ;-)
