> I don’t have anything insightful to contribute, but want to point out that in Emacs, “language” doesn’t always mean programming language. “Language” can also mean Chinese, English, etc, and Emacs are quite often used for editing natural language text. So it warrants some caution when using “language” to mean programming language specifically.

That's a good point.

But hopefully when the suffix -lang or -language is used in the symbol 
name, the preceding word(s) will make it unambiguous. But the mentions 
of "language" in the documentation would have to be more careful indeed 
(perhaps we'd call them "content type" after all, and :ruby-lang would 
be one of the content types).
