			concatMap(xs, fn)
			-----------------

			Return an array of concatenated elements by calling `fn(x, i)` for each element
			`x` and each index `i` in the array `xs`.

			When `fn(x, i)` returns an array, its result will be concatenated with the
			result array. If `fn(x, i)` returns anything else, that value will be pushed
			onto the end of the result array.
