I've wanted to implement that a few months ago, but Andi explained that
it's not really possible to write that function properly.
well, what was his reason? during some discussion we´ve found out that zend vars have a parameter is_ref and thus... no problem I`d think (var_dump() is capable of marking references too)
we´ve also found out that it´s complicated to find out to what the reference belongs too (for serializing), I think stas worked on this, not sure
regards
