+///
+/// This example section shows how to interact with WebAssembly process with ``Function``.
+///
+/// ### Print Int32 given by WebAssembly process
+///
+/// ```swift
+/// Function(store: store, parameters: [.i32]) { _, args in
+///     print(args[0])
+///     return []
+/// }
+/// ```
+///
+/// ### Print a UTF-8 string passed by a WebAssembly module instance
+///
+/// ```swift
+/// Function(store: store, parameters: [.i32, .i32]) { caller, args in
+///     let (stringPtr, stringLength) = (Int(args[0].i32), Int(args[1].i32))
+///     guard let memory = caller.instance?.exports[memory: "memory"] else {
+///         fatalError("Missing \"memory\" export")
+///     }

+///     print(String(decoding: memory.data[bytesRange], as: UTF8.self))
