Object.defineProperty Property not found in object literal

[borela]

The following code:

let a = {}
Object.defineProperty(a, 'someProp', {
  get() {
    return 42
  }
})

Did I do something wrong or is it a bug?

2: Object.defineProperty(a, 'someProp', {  
   ^ Object.defineProperty. Property not found in
2: Object.defineProperty(a, 'someProp', {                                        
                                        ^ object literal

Sure it's a bug.

See this poor definition.

I tried to improve at a bit (not enough for your case though) but with no success: maintainers are not too fast.

Pointing to this comment especially, too: #4742 (comment)

The definition has been updated in the JS lib, but it looks like value is still special-cased somewhere in the ML code.
