17.1 Emacs Lisp vs Common Lisp
Learning Emacs Lisp is useful and similar (but different from CL
- Dynamic scope is everywhere
- There are no reader (or reader-related) functions
- Does not support all the types that are supported in CL
- Incomplete implementation of CLOS (with the add-on EIEIO package)
- Not all of CL is supported
- No numerical tower support
