According to Knuth (quoted at http://tex.stackexchange.com/a/167443/1169):

    Knuth: So TeX is a programming language but I had to put in those features kicking and screaming.

But the quote equally shows how much it is not intended to be.

Yes, certainly, but you said (https://news.ycombinator.com/item?id=8615643):

> TeX is not a programming language.

rather than "TeX is not intended to be a programming language." It is nit-picking to be sure, but I think that, if the creator of a language (especially one who knows his stuff as Knuth does) says that it is a programming language, then it is.

Another appeal to (a lesser) authority—the TeX Users Group (https://www.tug.org/whatis.html):

    In summary, TeX is a special-purpose programming language that is the centerpiece of a typesetting system that produces publication quality mathematics (and surrounding text), available to and usable by individuals.
… and an appeal to the fact that people have written programs in it: http://stackoverflow.com/a/1931289.

(P.S. To "so, is XSLT a programming language because of, say, http://www.unidex.com/turing/utm.htm ?" I say "sure, why not?" What is the point of excluding something from being a programming language?)
