Empty List Block
Where Is It?
The Empty List block is located in the data statements drawer of the Blawx toolbox, in the List subdrawer.
What Does It Do?
The Empty List block is used to provide a value representing empty list. This can be used on its own to indicate that a list is completely empty, or it can be used in the "rest" portion of a First Rest Block to indicate that the list has no further elements.
Technical Details
The Empty List Block is a value block of the list type. It can be used anywhere a list is expected, including in attributes that have the list type, and list statement inputs expecting a list.
