Actually, proponents of its demise do take exception to its use syntactically,
mostly because of what it does to readability, especially in larger programs.
I have to think that the differences are generally understood, the question is
does the need for such subtle differences demand its presence, or could they
be handle better another way?

I agree, this is definitely more of a stylistic debate than anything else, and
I do use local frequently, myself, though just for private subs.
I am curious, however to see how often people use the localised scope function
in lieu of passing values or refs.
