Way to express "Simple" Expression Bodied Members

Auto ReadOnly Properties are convenient for when we can express our intention at initialization
```vbnet
Friend Overrides ReadOnly Property CanConstruct As Boolean = False
```
Sometime I like it to just as convenient to express what should happen at invocation, especially if it just a simple express / statement (IE a single Return / Throw ).

```vbnet
Friend Overrides ReadOnly Property CanConstruct As Boolean => Throw New NotSupportedException()
Friend Overrides ReadOnly Property CanConstruct As Boolean => Throw New NotImplementedException()
```
It would reduce the amount you'd have to read and type 80% per a "simple" property.
