Yes, according to my trivial benchmark, my patch puts a considerable
weight on the ZendEngine, to run twice as slowly as the current runtime in
the worst case. Seems no way, but I suppose it also sounds a reasonable
penalty of using references.
since one expects a 'pointer', rather than a copy.
Is there a way to warn when such a refstatement is detected, without causing slowdowns?
