Similarly, don't use def inside of a defn. Use let.

You're missing the point. A defn inside another defn doesn't do what you
think it does. defn always creates a global variabl

Nope. Just spent some time trying to duplicate the nested function bug
in a simpler context.
A pointer to the place where I should deposit code that manifests a

In the program below, if I use the commented-out version of thsolve
(program is the N queens puzzle), the with-local-vars construct causes
a NullPointerException when its block exits, after appearingt o work
correctly. The same thing happens if I use binding instead.
