I try to use it wherever possible as Igor recommends it but right now
Drupal doesn't cooperate. That's why I am hoping to push this change
forward in Drupal. I thought it would be interesting to know
internally how much is saved. Logfile pollution / possible error
string concatenation is a nice bonus (I know PHP's internal error
logging concatenates the error string and that's why it is good to
never have anything - even notice/info/etc. as it starts degrading
performance on some level)
