I may need to replace my dictionary, because the way I understand the
expression "like a function" is that the macro is called like function and it
behaves like a function, i.e. returns a value, IOW by using the macro its
expansion will perform the usual set of operation on the stack that a function
call involves (push parameters, return address, jump into function,
pop the return value...)
