Just a _write_ property:

void main() {

Application Output
Result: 9
Off the top of my head (C#, Delphi, Python) have them return
void. Maybe it's not so uncommon though.

A bit interesting to see I can declare a write property that
returns a value rather than void.
Why would a property return void. If anything, it would return
a non void:
auto a = someRange.front;
front is a property that returns a value.
It is usually more common to just have a read property that
returns a reference, which can be written to.
If the property needs an explicit write version, then usually,
returning a value is considered "costly".
But the point is you can do whatever you want anyways.
