+    """ 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.
