Use case: With promises, the expression body form of arrow functions is so convenient. Alas, `throw` being a statement, you can’t use it there. For example, the following code is not syntactically legal:
```js asyncFunc() .then(count => count >= 0 ? count : throw new Error(...)) .then(...) .catch(...); ``` Could `throw` be turned into an expression? -- Dr. Axel Rauschmayer a...@rauschma.de rauschma.de
