Comment (by ncohen):

 Defined as equivalence classes okay, but it stays abstract and you still
 have no coordinates. But then you say "I can either normalize the third
 coordinate if it is nonzero, otherwise I normalize the second
 coordinate,and if I can't I normalize the first".

 Well... I am used to defined this thing with "three kinds of points" :-P

 Anyway, if you can put this inside of the branch then no problem `:-)`
