Can it not be possible to use alias this on a private field?
struct Q
private:
int _x;
public:
alias _x this;
?
Seems to me that one does not always want the user to access the
internal value that is aliased ;/
Q q;q._x // error yet q, for all practical purposes is _x, we just stop the user from being able to directly access it.
For example, maybe I want to override opAssign on an int. The user can get around it by doing q._x. Seems like a bad idea.
