Is array () empty?

The is array () empty? block is a boolean block that reports true if the entered in array is empty and false otherwise. The default value for this block is "["A", "B", "C"]".
==Workaround==
This block can be worked around by checking if the length of the array is 0 using the equals block and the length of array () block.
