/// A macro to create a `json::Value` with a JSON-like syntax.
///
/// ## Usage
///
/// ### Literals
/// Create null, boolean, number, or string values.
///
/// ```
/// # use stdt::json;
/// let a = json!(null);
/// let b = json!(true);
/// let c = json!(123.45);
/// let d = json!("hello world");
/// ```
///
/// ### Arrays
/// Create an array from a list of values.
///
/// ```
/// # use stdt::json;
/// let arr = json!([1, "two", false, null, ["nested"]]);
/// ```
///
/// ### Objects
/// Create an object from key-value pairs. Keys must be string literals or expressions
/// that evaluate to a `String` or `&str`.
///
/// ```
/// # use stdt::json;
/// let obj = json!({
///     "name": "John Doe",
///     "age": 43,
///     "is_developer": true,
///     "phones": [
///         "+44 1234567",
///         "+44 2345678"
///     ]
/// });
