Should the new Mathematica 9 functionality of built-in units handling be extended from numerics and symbolics to graphics, too? For example, whereas the following is allowed with units . . . Plot[x^2, {x, Quantity[0, "Meters"], Quantity[1, "Meters"]}] . . . Quantity does not seem to be allowed in expressions such as: Graphics[Disk[{Quantity[0, "Meters"], Quantity[0, "Meters"]}, Quantity[2, "Meters"]]] The built-in QuantityMagnitude applied to the arguments can take care of that, but it seems to me that a fully integrated handling of units shouldn't require that -- unless, perhaps, the overhead of checking for units as arguments is just too high at present.
