Aggregate method invocations invoke aggregate methods repeatedly for each result of the sequential evaluation of its arguments or for each component of arrays and return a single result.
What is an invocation operator?

How methods are invoked in Python?

The Arguments property of the resulting InvocationExpression is empty if arguments is null. Otherwise, it contains the same elements as arguments except that some of these Expression objects may be quoted.
Is the argument property of the invocationexpression empty?
