Incorrect behaviour with array destructuring

[dsblv]

Babili seems to be misinterpreting array destructuring inside function bodies:

Input

const me = lyfe => {
  const [swag] = lyfe;
  return swag;
}

Output

const me=a=>{return a};

REPL

As you can see, it acts as if there's no destructuring going on at all.

It fails if you try to get more than one item:

Input

const me = lyfe => {
  const [swag, yolo] = lyfe;

  return swag && yolo;
}

Error message

repl: NodePath has been removed so is read-only. (This is an error on an internal node. Probably an internal error)

On the other hand, destructuring outside functions seems to be fine. Object destructuring also worked for me.
