Paul,

       Here's the section on equality (eq? eqv? and equal?):

       I've found the guile manual to be a helpful resource for
       learning to use Scheme.

Yes, I usually refer to the Guile manual although I try it only in
Friscobaldi.

Definitely consider trying out the Scheme "sandbox."  It's much more convenient for learning Scheme than embedding Scheme in ly files.

I found the videos on youtube series http://www.youtube.com/watch?

confusing.

The best help of all seems to be the display command that David showed. I
wish they give a little more prominence to it in the manuals and
tutorials.

Yes, it's a lifesaver.  I use format more often, because it makes constructing meaningful output a lot easier.  You will find--or maybe you already have!--that output to the console can get confusing.    For one thing, it's usually "out-of-order."

Anyway, glad to be of help!

David
