Extension of something written in a language like Haskell[0] definitely poses challenges. Even if the language makes it un-modifiable in your environment, there's no reason it can't be treated like a black-box component and used.

This could apply equally to Ruby, Java, bash, SQL, JavaScript, and Python depending on the makeup of the team supporting it.
