My new question is why we set the validationErrorListener function
pointer every time we go through the loop instead of just once.
Is this to protect against the possibility of the user's flowscript
messing with the pointer?
   

Answering myself: this is probably so we can pick up the brand new
instance of the variable "userErrors" to use in the function, right?

That's correct. If you're worried about performance, keep in mind that 
in this case the function body itself is only compiled once (when the 
script is loaded). Runtime compilation only occurs if you use eval() or 
the Function() constructor.
