[development] Ignoring Pass by Reference

[nan wich]

I am coding a hook_comment, which normally specifies "&$a1" in the parameters. 
It would be helpful to just add some additional stuff to that array before 
calling drupal_write_record. I have no idea whether the additional data would 
"upset" the comment module and I don't really need to modify the form data 
anyway. Would it be reasonable to just drop the ampersand from the parameters? I 
would definitely add a comment that I'm doing that.
