Yes, but was that the OP's question?

Well, if the question is "to reduce scope of variable as much as possible",

then I think that the issue of defining multiple procedures within the same

scope is a part of that question, even if it wasn't posited directly

Maybe it's time to point out that this question is in the Scheme-FAQ ;-)
[http://community.schemewiki.org/?scheme-faq-language] - Section
"Is there a way to define top-level closures?" (sorry, bad webdesign,
no wa to link directlyto the topic). The answer not only mentions
'define-values but also links to an implementation:
[http://community.schemewiki.org/?scheme-faq-macros#multidefine]
that uses 'syntax-rules

Thanks! :)
