+ 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.
