Livecoding a WebAssembly interpreter
summary
Livecodes an Elixir WebAssembly interpreter that reads .wasm binaries, parses sections and the code section, disassembles with wasm-objdump, and executes basic instructions (local.get 0x20, i32.const 0x41, sub 0x6B, call, if 0x04, end 0x0B). Builds a minimal module struct, supports the exported Fibonacci module and tests verify fib(4) == 5. Notes Lumen as an Erlang/Elixir-to-WASM effort and flags practical limits like no garbage collection and missing concurrency support.
