Merge

Merge expect 0 or more arguments.

No arguments

When called with no arguments merge takes all of the output values from the previous function and adds them to a single list.

1 or more arguments

When called with 1 or more arguments, the arguments are executed as a subquery on each of the output values from the previous function.

All values returned from subqueries across all input values are added to a single list.
