Against The Use Of Programming Languages in Configuration Files (taint.org)
2 points by micktwomey on Feb 18, 2011 | hide | past | favorite | 2 comments

If a configuration language is Turing-incomplete, configuration files written in it can be validated “offline”, ie. without executing the program it configures

This is exactly what I've been advocating recently. Less power is good, if it means you can validate your config files without first solving the halting problem.
