Hi,

as nobody was able to answer my question on IRC,
I just drop it here:

Is it useless (yet even counter-productive) to enable
pass_by_ref in an ARG_INFO section for a function or
method that expects an object?

By "counter-productive" I mean that I'd need to actually
pass an identifier for a variable.

Thanks,

Only use references when you need to be able to overwrite the variable.

Hi Wez Furlong, you wrote:

Ok, and what about return_by_ref?
