Shouldn't doubleMyValue(pt.x) be a compiler error if pt.x is a

auto __temp = pt.x;
doubleMyValue(__temp);
pt.x = __temp;
}
I believe this is something along the lines of what Swift and
C# do as well.
Or something... a DIP to fix properties anyone? :)

I'm not sure your rewrite is good though, because it does not
preserve aliasing during the function call.
You mean if __temp is modified in the doubleMyValue and pt.x
aliases something else? Or? Wouldn't the assignment back "just
work"?
And is there a rewrite that would work then?
