In dialog, if we close it giving `false` as a result i.e.
```
this.dialog.close(false)
```
Actual return is empty object.
Additional thing is result itself in `DialogRef` is force-typed as `DialogResult` despite that actual `dialogRef.close()` allows us to return any value.In such case I'd understand mapping to empty object (probably some truthy-based if which maps to empty object) but then close method should also force-type taken argument. So can we return any value or not?
Ideally it should return `undefined` in case of no result value is provided (also mapped to empty object) and return `false` if we return `false`
Hi Dominik,
My last reply might not have been constructed correctly and I do apologize for that. What I meant is that the following sentence from the close API isn't correct:
`When called with an argument, the result Observable will hold the provided value.`
This means that the return argument cannot be a custom value set by the developer and the instance will be always closed with DialogResult which is the currently clicked action or DialogCloseResult which is an empty object in case the `X` button was clicked.
I hope this explains the exact issue in our documentation and that a value set by the developer won't be returned as a result.
