     9  # `merge` Function
    10  
    11  `merge` takes an arbitrary number of maps and returns a single map that
    12  contains a merged set of elements from all of the maps.
    13  
    14  If more than one given map defines the same key then the one that is later
    15  in the argument sequence takes precedence.
    16  
    17  ## Examples
    18  
    19  ```shell-session
    20  > merge({"a"="b", "c"="d"}, {"e"="f", "c"="z"})
    21  {
    22    "a" = "b"
    23    "c" = "z"
    24    "e" = "f"
    25  }
    26  ```
