Being able to call finctions would be great, and would also suppress the
need for texture or pigment evaluation...
About the "if" function, it could also be possible to have something
like the well-known cryptic a?b:c syntax.
Adding local variables and loops would probably make things quite
different. Could you elaborate on a possible syntax? Did you think about
some lisp-like or RPN (a la PostScript) method?
