I'm not sure what you're suggesting here.

I can't test for type('RANDOM') because I'm not in control of what users might supply as a parameter when they use my program. My program expects an expression (DOM_SYMBOLIC) as its parameter and type(part('expression',0)) is DOM_STRING for every expression.
