Well, that may be true in math; but there's no reason why it has to be
true in Perl6 (using the Math::Perverse module?)
Imagine

.... $b = undef but DivZero(7) but Overload('*' => sub ($rhs) { $rhs==0 ? 7 :
.... })

I.e. you can use a runtime property to remember the value that was
divided by zero. I'm not sure what the correct syntax is to make that
really clean: hopefully the DivZero property could do the Overload.
