groovy Spread Operator Calling a method
Example
assert ['cat', 'dog', 'fish']*.length() == [3, 3, 4]
Note that when mixing types in the collection if the method not exists on some of the elements, a groovy.lang.MissingMethodException could be thrown:
['cat', 'dog', 'fish',3]*.length()
// it throws groovy.lang.MissingMethodException: No signature of method: java.lang.Integer.length()
