Feature Request: Light weight property declaration

Sometimes a class has many properties with the same type.
For example

```
public class Person
{
  public string FirstName { get;set; }
  public string LastName { get;set; }
  public string EmailAddress { get;set; }
}
```

Would become:

```
public class Person
{
  public string FirstName, LastName, EmailAddress { get;set; }
}
```
