No mainstream language that I am aware of uses the term "Box", while they almost all have something similar in concept, if not identical.

Python, Ruby, and JavaScript all have exclusively boxed values. "Everything is an object".
I'm not sure what languages you use but that pretty dramatically covers most of the mainstream (top 10 at least).
