Subject: Re: Passing procedures as parameters to procedures.

I actually think that in languages at the level of Ada/C etc, the notion of
pointer to procedure is clearer than the idea of a procedure as a value.
An interesting note here is that one Algol-68 text book contained in its
helpful advice the suggestion that it was better to pass procedures by
reference rather than by value, because it would avoid inefficient copying
of the code of the procedure. This may be an extreme case, but it is a nice
indication of the confusion that can be caused by considering procedures as
values in this level of language.
