Hmm, read-macros seem indeed a lot misunderstood. NEVER use a read-macro
to insert values which are defined at *run*time! As the name says, they
are evaulated at *read* time!
You could do this:
: (let X (+ 3 4) (glue " " (list "Number" X `(- 4 9))))
(the second read-macro is OK, as the (- 4 9) may be evaluated at
read-time)
