<div>
<pre>Right now, the parser eagerly reports an error when parsing an ObjectPattern (with DestructuringKind::DestructureToLet), as soon as it encounters the identifier "let" is encountered, without knowing if "let" is the intended destructuring target / binding identifier or not.
Example code:
```
let {let: a} = {let: 1 }
```
This should declare a lexical variable `a` initialized to `1`, but instead reports a SyntaxError. It's just a case of reporting the error a bit too early, before it's known whether it's the binding target or not. Easy fix, good first bug :)</pre>
