I had a round of this not so long ago on the work application: it is much easier to get away with locally modifying CPAN modules to avoid such things than to modify the ones bundled with perl, which are likely to be depended on by far more things. Carp usually gets invoked for two reasons: to report a fatal error (in which case if that's the only use, that's soon enough to be loading it), and to lie about where an error/warning was found (which I'd almost always rather it didn't do). I find it great to get a stack trace for the occasional hard debugging problem, but I'd love to see an end to the habit of loading it unnecessarily, and I think the core is the only possible place to start improving that. (I hate Exporter too, but that's a rant for another day.) Hugo
