This is an opportunity to learn. The way WebAssembly is defined is the standard way PL semantics are defined.

WebAssembly isn't a programming language, it's an ISA or a bytecode VM. They've defined it in a very over-engineered way, with different representations all the way through. It has created issues for people working on assemblers and code generation because it's hard to choose a good representation for compilers to generate. This all could have been avoided.
