I've thought about adding a builtin called "defined" or "isnull" that will check if a bind variable, or internal is null. I don't want to get in the mess of passing nulls around unless there's good reason. A real life valid example if it were to actually allow the assignment vs the comparison of undefs...

I'll fix my psuedocode tomorrow. I did it in word. Stupid grammar checker. :)
