Comment (by mbejger):

 Dear All, I have added a newer patch with an additional switch that allows
 for omitting the arguments of a function:

 {{{
 var('x y z'); f = function('f', x, y, z)
 f.diff(x,z,y,z)
 D[0, 1, 2, 2](f)(x, y, z)
 from sage.symbolic.pynac import omit_function_args
 omit_function_args(True)
 D[0, 1, 2, 2](f)
 }}}
