+/* IMPORTANT NOTE:
+ *  When the <il_operand> exists, and to make it easier to handle the <il_operand> as a general case (i.e. without C++ code handling this as a special case), 
+ *  we will create an equivalent LD <il_operand> IL instruction, and prepend it into the <simple_instr_list>. 
+ *  The remainder of the compiler may from now on assume that the code being compiled does not contain any IL code like
+ *     LD 1
+ *     ADD ( 2
+ *        SUB 3
+ *        )
+ *
+ * but instead, the equivalent code
+ *     LD 1
+ *     ADD ( 
+ *        LD  2
+ *        SUB 3
+ *        )
+ *
+ * Note, however, that in the first case, we still store in the il_expression_c a pointer to the <il_operand> (the literal '2' in the above example), in case
+ * somewhere further on in the compiler we really want to handle it as a special case. To handle it as a special case, it should be easy to simply delete the first
+ * artificial entry in <simple_instr_list> with il_expression->simple_instr_list->remove_element(0)  !!

  * Note: Bison is getting confused with the use of il_expr_operator,
