It's here: http://www.d-p-l.org/template.html#variadic-templates "A Tuple is not a type, an expression, or a symbol. It is a sequence of any mix of types, expressions or symbols." The language terminology is easily confused with the constructs that phobos defines, where TypeTuple and Tuple mean different things.
