I think people got it. But it's not a property. Your one-liner seems to be
equivalent to a field. Except, I guess, that you can't take the address.

The whole idea of a property is that it can have non-trivial getter/setter
functions. Like a read-only property of a Line, that returns its length
automatically calculated from its two points. Or a getter and setter that
keep a log of all accesses to the information.

My favorite example is of a Color class, that internally stores its value in
the RGB model, but has properties to read and change its value through the
HSV and HSL models as well.
