array_filter?(filter) private

When an array is expected, you must specify an array explicitly using the following format:

params.expect(comments: [[:flavor]])

Which will match only the following array formats:

{ pies: [{ flavor: "rhubarb" }, { flavor: "apple" }] }
{ pies: { "0" => { flavor: "key lime" }, "1" =>  { flavor: "mince" } } }

When using `permit`, arrays are specified the same way as hashes:

params.expect(pies: [:flavor])

In this case, `permit` would also allow matching with a hash (or vice versa):

{ pies: { flavor: "cherry" } }
