WASM is not positioning itself as a high-level application development platform. It's specifically meant to co-exist with ECMAScript (which is the app "glue"). It's meant to out-source computationally-intensive functions to, nothing more. If you embrace only the good / modern parts of ES6/ES7, you can really write elegant, modern, functional-style code. Not sure there is much left to complain about, other than the lack of built-in type system, which many others (but certainly not me) argue is a good thing.
