+//! Example:

+//! ```
+//! use nettext::enc::*;
+//!
+//! let nettext_encoding = list([
+//!     string("CALL").unwrap(),
+//!     string("myfunction").unwrap(),
+//!     dict([
+//!         ("a", string("hello").unwrap()),
+//!         ("b", string("world").unwrap()),
+//!         ("c", raw(b"{ a = 12, b = 42 }").unwrap()),
+//!         ("d", bytes_split(&((0..128u8).collect::<Vec<_>>()))),
+//!     ]),
+//! ]).unwrap().encode();
+//! ```
