I would like it, because the user and reader sees what to do (draw2d) and which object
(the term [x^2,..]).

Hm. Could become cryptic, the first version is contextfree understandable - this could be
helpful for beginners and occasional users. Shortcuts could be of value in the
construction of longer grapical scenes.

Yes, I think this is very flexible and allows clearly constructed graphical scenes.
Anyway: in my opinion a smart brillant graphical maschine is the killing application for a
general purpose CAS - it is crucial and often decides if a user (especially students!) is
attracted to use a CAS or not. What currently is to be seen is very promising.
PS: maybe one could integrate the great efforts of Jaime and other developers e.g. write
draw2d( .., directionfield(..)) instead of plotdf(..) etc.
The aim is to draw 'something' in 2D/3D using a unified action verb and afterwards
specifing the object.
Thank you all for the lively and prosperous existence of Maxima.
