Glad it helped.  In general, I think it would be good if more
Emacs Dev hackers were a bit more familiar with Common Lisp.

"Common Lisp The Language" is very readable, and it explicitly
presents the _reasons_ for many of the design decisions etc.

You can read it from front to back.  It is truly a pleasure to
dig into, and Guy Steele is a good writer.  Consider curling up
with it on one of these cold or rainy nights.  You won't regret it.

I still have and use the first edition.  The 2nd is longer and
includes `loop', CLOS, etc. but the meat is essentially the same.
