Have to concur. SO many people grab Python or Javascript for a 'quick short script' and it turns into a real production system and then becomes un-maintainable. But F#, functional languages, they maybe take more time to learn, or become proficient, but the errors drop way down, because the langue doesn't allow those types of errors that are common in 'scripting' languages.
