No, by default $SCRIPT_NAME would print on every iteration because it's
a scalar variable, but you're right that's sort of ambiguous.

So, you're saying that we can have default and pad attributes on section
level which provide the general settings for any variable that's seen
inside the section, and then each variable can override that? Does the
default/pad attribute set on an outer section affect the inner ones too?
Is it getting too complicated? :)

BTW, you don't need to set default="", it's already implied if not specified.

So, now we have three attributes that can be specified for a variable,
'loop', 'default', and 'pad'. My gut feeling is telling me it's getting
a little too complicated.

I'd call it loopvars=$title,$description or something like that, to be
more explicit. The only problem I see with this is what if you want to
loop through all but one variable, but I guess then you can use that
'loop' attribute on the variable itself. Hmm, I need more comments. :)
