There's definitely some speed to be gained if _get_preload could tell its caller: here are some modules to add to the dependencies, but I just know they don't "use" anything so you don't need to scan them. Besides DateTime::Locale this could probably used for the Unicode modules. I thought about passing the "skip" hash parameter of scan_deps_static down to _get_preload, so that a custom preload entry could add stuff to the "skip" hash. But the keys of the "skip" hash are of no use to _get_preload's world view: one uses module _names_ , while the other uses actual file paths. However, I think the current Module::ScanDeps is a little buggy, because strace shows that scandeps.pl -e "use DateTime::Locale" scans each DateTime/Locale/*.pm no less than six (6) times and each .../unicore/lib/**.pl four times.
