Groovy: Closure Currying Example

Really simple example of closure currying so I do not forget it and hope that it helps someone else:
def addTo = { Map m, String k, Object v ->
    m[k] = v

Map elements = [:]

addTo elements, 'a', 1

def addTo2 = addTo.curry(elements)

addTo2 'c', 3

assert elements == ['a':1, 'c':3]
