Input Code

export default function() {}

Babylon Use

const babylon = require("babylon");
const src = "export default function() {}";
const ast = babylon.parse(src, { sourceType: "module" });
console.log(JSON.stringify(ast.program.body[0], undefined, 2));

Expected Behavior

Either:

• This should be parsed as a FunctionExpression.
• FunctionDeclaration may have a null id.

Current Behavior

Spec declares that FunctionDeclaration must not have a null id.

But in the output:

"declaration": {
  "type": "FunctionDeclaration",
  ...
  "id": null,
  ...
}
