I'm about the begin my Lisp journey but I have some questions....
1. Does the freeware version of LispWorks or Franz's Allegro have benefits over SBCL?
2. Should I learn Flavors in addition to CLOS?
3. Why do some programmers insist that dynamic scoping is better? I can't see the appeal of it.
4. How do I learn Scheme macros and Common Lisp macros?
