First, thanks for your wonderful little piece of software.

I was wondering if the grammar was allowing math expressions and advanced operators like cosine or sine ?
Furthermore it seems that few operations are possible on variable (define), especially if there are used with the gui.

here is a small example  to illustrate :
#define foo 30

rule R  maxdepth 6 {
  { x cos(foo) rx foo } R
  box
}
