-    """ PLEASE NOTE!  I just realized that I need to have a __str__ method on User
-    to get it to write the usernames back in the form when it redisplays them, since
-    this validator turns them into user objects instead.  This fact actually sounds dangerous
-    to me in the future, since it means I proably shouldn't be changing the data input
-    by the user right here in the validator, or the user will see the post-mangled data instead
-    of what they actually typed.  Hm.
-    
-    One solution to this could be to only look up the users after normal validation is over, 
-    and then manually add validation errors to the form if that fails.  But I think that kind of
-    sucks.  Perhaps the ideology in Formish, where they keep Validation and Conversion as
-    separate tasks, is a better way of doing it?  That way there is less risk of changing the user's
-    input -- you do that at the conversiot stage -- yet it is still encapsulated in the form workflow.
-    Hm.  But that means I'd have to query for the users in the validation step and throw them away,
-    or something equally stupid.  Guess there's no perfect solution here, but I thought it was
-    worth discussing.
-    
-    Btw, this is meant to be used by a field with multi user autocompletion on it (like on stackoverflow tags),
-    so the user should never actually submit anything invalid unless they disable javascript and force it.
