I think that in D, a tuple is a lexical construct and not a run-time
construct. This means that it only exists while the application is being
complied and once compiled a tuple has no run-time representation. It is an
aid to writing generic code because it allows you to specify a
list/se/sequence of Types that you can address indivually as if it was an
array of types. They are Types and not Data values.

Of course, I could be totally wrong as I haven't needed to use them yet.
