in reply to modules installed by default?

If you want a list of things not part of the core, this is a job for ExtUtils::Installed...

perl -MExtUtils::Installed -e '$i=new ExtUtils::Installed; print join(
+$/,$i->modules()),$/;'

You can also use this module to list the contents of the core (or any other module).

Remember, when you stare long into the abyss, you could have been home eating ice cream.
