Does that also apply to Golam's earlier comment

   (a) If we all agree that there is no ambiguity when the particular
        argument is a "symbolic variable" or "symbolic function" then
        we should typeset them as those found in text-books.
        Ex:
        (1)  D[0,0,0] (f)(x,y)    =>  \frac{\partial^3}{\partial x^3} f
(x,y)
        (2)  D[0] (f)(g(x,y), h(z)) =>  \frac{\partial}{\partial
g(x,y)} f(g(x,y), h(y))

so that we will no longer see nicely typeset partial derivatives even
in case (a)(1) (or even Leibniz notation at all?), or is it only in
the case (b) "when the argument is an expression"?    Thanks for the
clarification.
