6.7.1.2. Reflective Module.ResolveExport() - Review SyntaxError on circular dependencies

I believe this refers to circular references in the bindings setup. The point is I can't do:

a.js

export {a} from './b.js';

b.js

export {a} from './a.js';

So we stop circularity of bindings, not circularity of modules.

@guybedford is right: this part of the semantics treats re-export cycles as a static error, not cyclic module dependencies. Re-export cycles are nonsense: in the example above, a is not actually defined anywhere.
