   $sub_sep as the separator.
 
   You can also check for the existence of multi-dimensional array by
   looking for $sub_sep in the key.
 
-  Last, you need $sub_sep if you want to use the 'in' keyword.
+  If you want to use the 'in' keyword, use this syntax:
 
-      if ((1,2) in myArray)
+      if ([1,2] in myArray)
       {..}
 
-  doesn't work, but
-
-      if (("1" $sub_sep "2") in myArray)
-      {..}
-
-  does work.
-
   Note that if an array contains a value that is itself an array, you can
   apply the index operator more than once. For example
 
       subarray["a"] = "value"
       mainarray[1] = subarray
