Jose/Pepe has done this. afaiu I think it is a way to avoid unnecessary

I was going to ask: how? But then I realised it is completely possible to
define this as-is:
recur=: 13!:8@21
scope=: {{
old_recur=. recur
recur=: u
r=. u y
recur=: old_recur
r }}
Season with try. and ambivalence to taste.
(That said, you cannot retain the old behaviour of $: in cases where you
have not explicitly specified a scope.)
