/// Use for pattern matching on arrays where you don't care about the order of the items.
/// About the simplest case would be where you have 2 options and need exactly one to be `Some`:
/// ```
/// let input = [Some(42), None];
/// if let permute!([Some(n)], [None]) = input {
///     assert_eq!(n, 42);
/// }
/// ```
/// In this case it matches just like `[Some(n), None] | [None, Some(n)]`, but for more pattern groups it could save a lot more code.
/// The parameters are some number of (comma-separated, square-bracket-enclosed) groups of comma-separated patterns, each group should contain patterns which would match the same inputs, as the ordering of these doesn't need to be permuted.
