For the second example:
Why pass $this by reference? Specifically:
Occasionally, I'll see WP example code (like above) where the author
passes $this by reference.
Other examples, like:
... $this isn't passed by reference.
Sorry if this is a dumb question, but (within the context of coding
OOP for WP) how do I determine if I need to pass $this by reference?
Is there a good WP/PHP rule of thumb?
For the add_meta_box() example, I don't see any obvious reasons why
passing by reference is required and/or better than not. :D
