Comment:
The setref op does not mean pass by reference. Specifically, setref on
FixedPMCArray and descendants (including ResizablePMCArray) is an
extremely internal-ish operation that users should *not* be using.
The example code now segfaults. The segfault has nothing to do with the
return (the _dumper call can be moved to immediately after the setref for
the same effect) and everything to do with poking things that shouldn't be
poked.
