Huh? There's exactly the same number of function calls. And who said 
this was ever about performance?

Again, it's just different syntax for doing things we can already do. 
Even the object cascade operator is just hiding the assignment to a 
temporary variable - think of it like post-increment:

$bar = $foo; $foo = $foo + 1;
$bar = $foo++;

$bar = $foo; $foo->inc();
$bar = $foo->>inc();

(I'm not suggesting this is a literal use case for the operator, just 
highlighting the parallels; please don't start picking at it.)

Regards,
