Elsewhere I believe the order is not important if it is not ambiguous. Since we have to numbers they have to be in order - positive flex then negative flex if we want reasonable default.

Having good defaults is key here (just as it is with 'background' property)

	flex(1) 	means (preferred=auto, positive-flex=1, negative-flex=0)
	flex(auto) 	means (preferred=auto, positive-flex=1, negative-flex=0)
	flex(0) 	means (preferred=auto, no flexibility)

if this is really the way to go, it should probably accept unitless zero length at certain priority (first or last... I think last)

I'm confused. 'flex(auto 1 0)' is the same as 'flex(auto 0 1)' or 'flex(1 auto 0)'?
