See http://blitiri.com.ar/p/libfiu/ I've not used it, and I have no idea whether it works on either OpenBSD or Darwin, but I like the idea. I wonder how useful it would be to run against the perl test suite. Probably not very. We would need specific tests for error conditions, I expect. But running against those tests would be useful. -- Paul Johnson - paul@pjcj.net http://www.pjcj.netThread Previous | Thread Next
