Is this all the documentation there is for the use-clause for
anonymous closures?

http://us2.php.net/manual/en/functions.anonymous.php

For one, it would be nice to have documentation that explains whether
the variables listed in the use-clause are copied/referenced at
declaration-time or at call-time?

would be nice having more docs on that.
there are the two rfc's:  https://wiki.php.net/rfc/closures  and
https://wiki.php.net/rfc/closures/object-extension  but make sure to test
because AFAIR the rfc is a little bit behind the current implementation.
