!! Most of this file tests a known bug arrising from the interpreters 
!! error on reducing the types of arguments to the boolean and 
!! arithmetic operators.
!! A partial solution (step in the right direction) is
!!
!!  OPEN($cond) GSB($arg) M("==") GSB($arg) PROC(s_eq) END
!!  // Instead of the current lines
!!  //OPEN($cond) GSB(string_e) M("==") GSB(string_e) PROC(s_eq) END
!!  //OPEN($cond) GSB(num_e) M("==") GSB(num_e) PROC(s_eq) END
!!
!! Using the above solves the problems demonstrated in this file but 
!! creates new ones for ambiguity in operations like "A || B || C"
