Syntax? > User-defined functions? It's Lisp? Mainly the last. Once you've spent a week telling your stupid SVG "this triangle goes to (23.2, 5.7), and this other goes to (29.7, 6.2)" you want to be able to be more abstract and say "triangle C goes smack in the middle of A and B" and "circle X goes somewhere between Y and Z, but choose a spot which looks nice". You want programmability. Look into TiKZ (whether you end up using it or not) for some inspiration on what you might want a drawing program to do for you. Or Metapost: as an heir to Metafont, it probably has that declarative touch to it.
