As I understand it, 0/0 is an indeterminate form, which means that any value for z is admissible when x=0 and y=0. Hence, (x=0, y=0, z=1) should be kept as a solution.
Others, can you please help us with this one? Can we review the consequences of our decision to make intervals subsets of the real numbers, along with our decisions concerning decorations (and in particular, decorations corresponding to partial domains of definition)? Can we also review the corresponding sections of the standard draft, to make sure those sections are clear, and specify what it should be?
