associateBy
fun <T, K, V> Attribute<Iterable<T>>.associateBy(keySelector: (T) -> K, valueTransform: (T) -> V): Attribute<Map<K, V>>fun <T, K> Attribute<Iterable<T>>.associateBy(keySelector: (T) -> K): Attribute<Map<K, T>>
Same as associateBy, but accepts Attribute and returns a new Attribute.
Calling this function is equivalent to use transform and calling associateBy in the transformation function.
This is simply a convenience function.
