Some examples that demonstrate different aspects of the language:
* [sprocketnes], an NES emulator with no GC, using modern Rust conventions
* The language's general-purpose [hash] function, SipHash-2-4. Bit twiddling, OO, macros
* The standard library's [HashMap], a sendable hash map in an OO style
-* The extra library's [json] module. Enums and pattern matching
