Any sizable Lisp applications will make extensive use of macros. Emacs and magic ( the web framework) come to mind. My experience has shown that nobody but the person who writes the DSL extension can maintain their code. The benefits of extending a language in a domain specific manner are exaggerated. My observation is that macros are important to Lisp and it's derivative because they lack libraries to begin with. Common problems solved using macros in Lisp and friends are solved using specialized libraries in most other languages. And I like the specialized libraries route. Meta-programming just doesn't tickle my fancy.

How's this a good thing? I don't need a Python environment to grok Python code. > I don't agree with a lot of what you say in this paragraph, but I > you're right that libraries are crucial.

People only contribute to things they understand and appreciate. More people would be writing Lisp libraries if it was worthwhile. Apparently, it doesn't seem to be. A few years ago, I tried to write an editor is Scheme. The experience was appalling. I was able to write a fully functional prototype editor in less than a week in Python. Shockingly, at the time, I had no experience in Python. Guess which community I was inclined to contribute to afterwards. I hear stories similar to mine time and again, yet the Lisp community won't take heed. They'd rather squeal about the superiority of macros and whine about their frustrations in Python news groups. -- http://mail.python.org/mailman/listinfo/python-list
