At this point, I respectfully disagree. To say it's not supported is one
thing but to say it's better or more efficient convincingly requires more.
Tell me why :)
Who's repeating/repassing?
I'm under the impression it would be faster for the interpreter if the
statement were chained, also a copy (memory) of the object would be not be
required. Oops, I mis-spoke, actually a copy would be required due to the
the referencing conventions - perhaps this is not useful anyway given what I
really want is...
$tmp =& $foo->get("bar"); // note the &
$tmp->alterBarSomeWay(); // $tmp->getBaz();
No way to do that in one line. I think the reference conventions are odd.
I can pass a variable to a function not knowing it may be referenced and
altered (unless I check the signature), but I have to know that what I'm
receiving from a function is a reference in order to grab it properly!?
I wish I knew why these decisions went the way the did.
