suggested modification to the 'mle' documentation?

Hello: 

      I wish to again express my appreciation to all who have 
contributed to making R what it is today. 

      At this moment, I'm particularly grateful for whoever modified the 
'mle' code so data no longer need be passed via global variables.  I 
remember struggling with this a couple of years ago, and I only today 
discovered that it is no longer the case. 

      I'd like to suggest that the 'mle' help file be modified to 
advertise this fact, e.g., by adding one of the two examples appearing 
below. 
  

      Best Wishes,
      Spencer Graves
