Ehhhhhh. I get the sentiment, but I think this really depends on what the "main" language is and how amenable it is to scripting.

Personally, I prefer writing shell scripts regardless of what the main language is in a given project. They're portable (more or less), and can e.g. detect missing dependencies and install them if necessary, which isn't possible with the main language if you're missing its compiler or interpreter.
