> all the functions included in the drill distirbution are scanned in the classpath and
then parsed with janino at startup.
> This slows down startup and unit tests.
> If they were in their own module it would be possible to preprocess at build time and
have a much better startup time, including in tests.
> The classpath scanning library used (reflections) already has a mechanism to persist
its result.
