[plt-scheme] How do I convert (values ...) to something I can do something with?

Stylistically, is one better/more idiomatic than the other? I thought
about returning a list, but I have this aversion to complex nested
structures that aren't self-descriptive. (Yeah, I know--if
s-expressions freak me out, I'm looking for trouble coding in Scheme.)
I could define a struct so that the parts have names; maybe that's the
best thing to do.

I guess I decided to return multiple-values because it forces me to
check myself. I can't just assign the return value from the function
to a single variable, so if I screw up and forget that it returns
multiple values, I should get an error fairly early. Within my code,
the multiple-value thing isn't a problem at all. It's just when I was
trying to write test cases that it became annoying.

Does anyone else sometimes feel like you're learning a foreign
language by listening to tapes? I have this constant worry that, while
I think I'm speaking Scheme, when I finally start talking to native
speakers, they're going to find my accent either incomprehensible or
really funny.
