is_reference() ?

Hi, I recently had a discussion with Alexander Aulbach (submitter of bug reports with unset() and the inconsistencies with unset($foo) and unset($bar["bla"]) (the latter works, the former not)) and we agreed that there definitively would be need of a funtion called is_reference(varname) Sometimes we would like to know if $foo is a references variable or not (e.g. to ship around the unset() bug issue).
