Auto-implemented Property with Identified backing Field

While I'm writing this property:

```
Public Property NewYork() As Integer
Get
Return Me("NewYork")
End Get
Set
Me("NewYork") = Value
End Set
End Property
```

I asked myself: Why can't it be auto-implemented?

So, could it be like this:
`Public Property NewYork(Me("NewYork")) As Integer`

Or like this:

`Public Property NewYork() As Integer {Me("NewYork")}`

This is not only for dictionary keys. It's general for any property that uses an existing object instead of a backing filed

`Public Property Prop1(Storage) As Integer`

Or:

`Public Property Prop1() As Integer {Storage}`

I hope to hear other syntax suggestions.
