Regular expressions are a GOOD example of where domain-specific languages are beneficial.

A turing complete sendmail.cf is a domain-specific language gone BAD.

Apache rewrite rules, for example, use regular expressions - that is good. They could have invented their own language to match urls - that would have been bad.

Should I have added "or SQL or regular expressions" to the last sentance of my original comment?
