One line Tree in Groovy

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() } }

Two line Tree in Groovy

Update!

Wow... Kiyotaka Oku's fork of this shows how to do it in one line :-)
