[Cl-perec-devel] Bug with accessors to boolean field.

The default accessors for boolean fields end in "-p", rather than "-of".
So for your example, use (f2-p e).  (I just learned this today ;-)

You can safely use T and NIL instead of #T and #F; these are reader
macros, not sure where they are defined (maybe cl-syntax-sugar) but you
need to import them or :use that package... or just define them
yourself.  I myself prefer sticking with T and NIL.
