[plt-scheme] signed unit syntax

Matthias has been my guide on units and provided a response to the
following question I posted:

"I have an application in which I'd like to be able to run a procedure,
(in the example below, the execute procedure) and to have the
variables, procedures, etc. that are used by the procedure vary - with
different definitions of the variables, procedures, etc. being loaded
from disk."

I've found this idiom (which can be generalized using the approach in
his response in this thread) to be invaluable - thanks Matthias!

Cheers,
Dave
