Yes, we've all been wondering what the risk is there. Worst case I guess we could grep through the Ruby source I suppose.

Doesn't that just lead to a "cargo cult?" :-) I wondered if maybe Object#equal? used object_id to determine if the two objects were the same. But that theory was disproven by a test that undef'd it first: equal? ran just fine. I even tried def'ing equal? to raise an exception and that showed it never got invoked by equal? anyway. -Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
