IFF we allow "+" to be a procedure as well as a function,
then, as a procedure, it can not return a result [1].
Therefore, neither "+" above could be the procedure.

However, if we allow "+" to be a procedure, and allow
it to be called with the syntax

    i + 1;

then we would have to decide whether to allow

    i + j + 1;

and if so, how to define its meaning.


[1] Remember, in Ada, (unlike C), you cannot change
     a function to a procedure by discarding its result.
