http://d-programming-language.org/tuple.html

You may find the newsgroup digitalmars.D.learn more appropriate for such  
questions :)

Probably nowhere. There are no built-in tuples in D. std.typecons.Tuple is 
probably what you're looking for. It's a struct which defines a tuple. There's 
also std.typetuple.TypeTuple which is a compile time construct useful in meta-
programming. But there is no tuple built into D. There has been some 
discussion of improving the syntactic sugar with regards to std.typecons.Tuple 
- either via some additional templates or possibly adding something to the 
language itself - but that hasn't happened yet, and there are no tuples built 
into D.

Then if they are just a library artifact, should the terms TypeTuple and \
ExpressionTuple be present in the language reference?

Maybe 'tuple' can slip in, since it is a more generic term, but even that
is doubtful since it causes people to hunt through the reference to see
what facilities D provides.

There's .tupleof, I would consider that built-in.

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.

True. I forgot about that one. IIRC, that's effectively a TypeTuple, but 
TypeTuple is in std.typetuple, so I'm not quite sure what the deal with that 
is. Regardless, TypeTuple has always been a bit confusing. It doesn't contain 
just types, and it's not really a tuple. It's probably a bit late in the game 
to give it a better name though. Adding tuples to the language like Bearophile 
keeps pushing for would probably make things even more confusing.
