I have a question about passing of array parameters in Oberon-2.
Lets say I want to write a procedure to print a string passed in to
it.  I would do something like:

        PROCEDURE PrintString(VAR s : ARRAY OF CHAR);
        BEGIN
           (* print string here *)
        END Print String.

But then the following would not work.

        PrintString("Hello");
        
Because a constant is being passed in.  So instead, the PrintString
routine would be:

        PROCEDURE PrintString(s : ARRAY OF CHAR);
        BEGIN
           (* print string here *)
        END Print String.

However; will "Hello" be copied onto the stack?  That seems very wasteful,
but I don't see any other way around it.  I am writing an Oberon-2
interpreter and I can't take this level of inefficiency.
