If it's a non-numeric it won't do anything.  HC and its progeny is
smart when it comes to variable...err...container handling.

Thankfully, unlike most 3 and 4GL's, HC, RR et al aren't crippled by
this notion.  The first time you reference a container it is
automatically initialized to empty.

That would be unusual in this branch of CS.  WIthout testing, I would
be willing to bet that it is faster to decrement your starting point
and use "after" than it is to use "before".
