But the leak is not with $x, it's with what $_[0] is; $x is just a reference to that, and the reassignment in the second line should reassign $x, and decrement the ref count for what $x is pointing to at that point. So, it all depends on what make_something_from() does with the $x's referent. (darren) -- Great minds discuss ideas. Average minds discuss events. Small minds discuss people. -- Admiral Hyman G.
