WASM

WebAssembly or wasm is a safe, efficient and portable low-level bytecode format for in-browser client-side scripting (though can be also used in non-web environments). WASM is an open standard currently under development by the W3C. Its initial aim is to support compilation from C and C++, though other source languages such as Rust are also supported.

Current version is 0x1 (https://github.com/WebAssembly/design/blob/d9bff35e1389ba11c98ccee8cde72bb2f30e922c/BinaryEncoding.md). Bin support aims to be more flexible than the spec and current implementations, for example, it allows disordered and repeated sections, and tries to keep parsing after an invalid section is fou
