A category for any language that people assert is "based" in something.
E.g., PrototypeBasedLanguage, TupleBasedLanguage?, etc.
I'm disappointed I was hoping this was about languages based on CategoryTheory, like CharityLanguage.
That's what SaundersMacLane? gets for picking such a generic name for the math. Like how CategoryTheory needs a disclaimer that "This is not a category for theories."
Yes, but, this is probably the only wiki category page that applies also to itself --- meaning, CategoryBasedLanguage can itself serve as a page describing category-based languages. :-)
