@ -83,6 +83,13 @@ Return the list of objects that directly refer to any of objs. This
function will only locate those containers which support garbage
collection; extension types which do refer to other objects but do not
support garbage collection will not be found.
Note that objects which have already been dereferenced, but which live
in cycles and have not yet been collected by the garbage collector can
be listed among the resulting referrers. To get only currently live
objects, call \function{collect()} before calling
\function{get_referrers()}.
