TeX as a programming language is a derivative of LISP and in this sense it is 
though not functional. Now, a language that is procedural is (almost?) an 
programming language and frankly I don't understand how an imperative language 
can be
declarative at the same time. Also, informally speaking, when one says a 
language is dynamic
or static, he/she refers to the type system of the language.
