The other day, I saw Harold Cooper's One-line tree in Python via autovivication, and wondered if the same thing was possible in Groovy.
The answer is yes! But you need to define the variable tree before you can assign it to the self-referential withDefault closure, hence with Groovy, it's a two-line solution ;-)
Anyway, given:
def tree = { [:].withDefault{ owner.call() } }
