To rephrase the problem:
Assuming `next` was never defined.
```js
let a = { next() { next() } };
a.next();
```
The result of running this code is runtime error or infinite recursion?
I tried to find the answer in the spec, but the initialization and calling of a
function object is a bit overwhelming for me.
The evaluation of FunctionExpression contains a step "Call the
CreateImmutableBinding concrete method of envRec passing name as the argument.”
together with "Call the InitializeBinding concrete method of envRec passing
name and closure as the arguments. I" guess that’s the steps enable directly
calling function name in the function body?
And since DefineMethod doesn’t have such steps, is it correct to assume the
above snippet should result in a runtime error?
Thanks.
