enum JSON_TYPE: byte;
  JSON type enumeration

  STRING
  INTEGER
  UINTEGER
  FLOAT
  OBJECT
  ARRAY
  TRUE
  FALSE
  NULL
    Indicates the type of a JSONValue.

struct JSONValue;
  JSON value node

  const @property JSON_TYPE type();
    Specifies the type of the value stored in this structure.

  deprecated @property JSON_TYPE type(JSON_TYPE newType);
    Deprecated. Instead, please assign the value with the adequate type to JSONValue directly. This will be removed in June 2015.

    Sets the type of this JSONValue. Previous content is cleared.

  inout @property inout(string) str();
  @property string str(string v);
    Value getter/setter for JSON_TYPE.STRING.

    Throws JSONException for read access if type is not JSON_TYPE.STRING.

  inout @property inout(long) integer();
  @property long integer(long v);
    Value getter/setter for JSON_TYPE.INTEGER.

    Throws JSONException for read access if type is not JSON_TYPE.INTEGER.

  inout @property inout(ulong) uinteger();
  @property ulong uinteger(ulong v);
    Value getter/setter for JSON_TYPE.UINTEGER.

    Throws JSONException for read access if type is not JSON_TYPE.UINTEGER.

  inout @property inout(double) floating();
  @property double floating(double v);
    Value getter/setter for JSON_TYPE.FLOAT.

    Throws JSONException for read access if type is not JSON_TYPE.FLOAT.

  inout @property ref inout(JSONValue[string]) object();
  @property JSONValue[string] object(JSONValue[string] v);
    Value getter/setter for JSON_TYPE.OBJECT.

    Throws JSONException for read access if type is not JSON_TYPE.OBJECT.

  inout @property ref inout(JSONValue[]) array();
  @property JSONValue[] array(JSONValue[] v);
    Value getter/setter for JSON_TYPE.ARRAY.

    Throws JSONException for read access if type is not JSON_TYPE.ARRAY.

  this(T)(T arg) if (!isStaticArray!T);
  this(T)(ref T arg) if (isStaticArray!T);
  inout this(T : JSONValue)(inout T arg);
    Constructor for JSONValue. If arg is a JSONValue its value and type will be copied to the new JSONValue. Note that this is a shallow copy: if type is JSON_TYPE.OBJECT or JSON_TYPE.ARRAY then only the reference to the data will be copied. Otherwise, arg must be implicitly convertible to one of the following types: typeof(null), string, ulong, long, double, an associative array V[K] for any V and K i.e. a JSON object, any array or bool. The type will be set accordingly.

  inout ref inout(JSONValue) opIndex(size_t i);
    Array syntax for json arrays.

    Throws JSONException if type is not JSON_TYPE.ARRAY.

  inout ref inout(JSONValue) opIndex(string k);
    Hash syntax for json objects.

    Throws JSONException if type is not JSON_TYPE.OBJECT.

  int opApply(int delegate(size_t index, ref JSONValue) dg);
    Implements the foreach opApply interface for json arrays.

  int opApply(int delegate(string key, ref JSONValue) dg);
    Implements the foreach opApply interface for json objects.

  const string toString();
    Implicitly calls toJSON on this JSONValue.

  const string toPrettyString();
    Implicitly calls toJSON on this JSONValue, like toString, but

    also passes true as pretty argument.

JSONValue parseJSON(T)(T json, int maxDepth = -1) if (isInputRange!T);
  Parses a serialized string and returns a tree of JSON values.

string toJSON(in JSONValue* root, in bool pretty = false);
  Takes a tree of JSON values and returns the serialized string.

  If pretty is false no whitespaces are generated. If pretty is true serialized string is formatted to be human-readable. No exact formatting layout is guaranteed in the latter case.

class JSONException: object.Exception;
  Exception thrown on JSON errors
