\n\nRBBJSON enables flexible JSON traversal at runtime and [JSONPath]-like querying for rapid prototyping.\n\nUse `JSONDecoder` to create an `RBBJSON` struct, then traverse it using [dynamic member lookup][dml]:\n\n```swift\nlet json = try JSONDecoder().decode(RBBJSON.self, from: data)\n\njson.firstName // RBBJSON.string(\"John\")\njson.lastName // RBBJSON.string(\"Appleseed\")\njson.age // RBBJSON.number(26)\njson.invalidKey // RBBJSON.null\njson.phoneNumbers[0] // RBBJSON.string(\"+14086065775\")\n```\n\nIf you want to access a value that coincides with a Swift-defined property, use a `String` subscript instead:\n\n```swift\njson.office.map // Error: Maps to Sequence.map\njson.office[\"map\"] // RBBJSON.string(\"https://maps.apple.com/?q=IL1\")\n```\n\nTo unbox a JSON value, use one of the failable initializers:\n\n```swift\nString(json.firstName) // \"John\"\nString(json.lastName) // \"Appleseed\"\nString(json.age) // nil\n\nInt(json.age) // 26\nDouble(json.age) // 26.0\n```\n\nYou can also make use of a [JSONPath]-inspired Query syntax to find nested data inside a JSON structure.\n\nFor example, given:\n\n```json\n{ \n \"store\": {\n \"book\": [ \n { \n \"category\": \"reference\",\n \"author\": \"Nigel Rees\",\n \"title\": \"Sayings of the Century\",\n \"price\": 8.95\n },\n { \n \"category\": \"fiction\",\n \"author\": \"Evelyn Waugh\",\n \"title\": \"Sword of Honour\",\n \"price\": 12.99\n },\n { \n \"category\": \"fiction\",\n \"author\": \"Herman Melville\",\n \"title\": \"Moby Dick\",\n \"isbn\": \"0-553-21311-3\",\n \"price\": 8.99\n },\n { \n \"category\": \"fiction\",\n \"author\": \"J.
