As far as I know, the obove kind of thing isn't possible with

...and if the specification is changed so that:
struct S
{
T _prop;
@property T prop() const
{
return _prop;
}
@property void prop(T t)
{
assert(t <= 5);
_prop = t;

S s;
s.prop += 3;
...gets lowered to s.prop = (s.prop + 3); Then that sucks because
now T is forced to provide the binary + operator.
