> If you think of vectors as specifying directions, then normalization
gives you a "random but fixed" vector pointing in the same direction as
the original. If you store a lot of directions, then comparing normalized
vectors is quicker than using dot-products.
My point was that if there isn't a consistent way to do it that makes
everybody happy... At the least, can we find another name for the current
function when you make that vote on sage-devel? Someone will presumably
need it...
