Re: [pro] The Best Examples of "Code is Data"

1. Doug Hoyte's book Let Over Lambda, chapter 6.3 Alet and Finite State Machines, raised my macrology to a new level. I used his ideas to implement a full-blown hierarchical state machine macro(s) (roughly 200 lines of CL, too large to post here). The hierarchical state machine paradigm is great for programming reactive things, e.g. gui's, hardware controllers, etc.

This is an interesting and original book. The techniques he likes, including "anamorphic macros", have generally been frowned upon by the community. However, I don't want to object to his approach just because it's different from that if me and my friends. Who know, he might be on to something. I think it's extremely impressive that he was able to get a book published on a topic with such a small audience: good for him!

2. On Lisp's and PAIP's prolog compiler macros. The code itself is a nice brain stretcher. I use cl prolog to parse difficult languages (e.g. diagram-based languages).
