What is a tuple and why should one care?

[Justin Johansson]

There's a lot of (imho, pointless) discussion going on about
tuples in D.

I've asked before and haven't any illumination, especially of Walter.

In the context of D, can someone please enlighten me as to exactly
what a tuple is supposed to be.

The discussion so far appears to me to be focusing on syntax
for these "tuple thing-a-m-be's" without defining what the bloody
thing-are-might-be's are.

Thanks in advance for zen enlightenment,
Justin Johansson
