In addition, XQuery 4 will allow all of us to write self-referencing variable declarations (it’s already supported by the latest snapshot):
declare variable $factorial := fn($x) { if($x > 1) then $x + $factorial($x - 1) else $x }; $factorial(5)
Hmm, what if there's a $factorial in scope already? (this is a technique i teach for taking advantage of closures to hide data)
