Please think long and hard about using such an extension, even if
it is available.  You'll save a lot of work on the part of the
person who has to port the code next year to another compiler or
environment that doesn't have the neat extension.
And remember, that person may be you.

Stephen gives some good approaches to identifying the length and/or
end of the list -- use them!
