/* Since I expect this little function to be discovered sooner or later I'll better 
   add a little explanation. Does this qualify as passive aggressive? Maybe. But I'm 
   a voluntary contributor here and think I'm under no obligation to read every statement
   from every user. Some people are just the equivalent of a red cloth for me, and 
   everybody will benefit from me just ignoring those people. So if it hurts noone I believe
   it is ok for me to make my work here as pleasant as possible.
