Postblit does not cover cases when object assigned to struct is of different type - this is main purpose of overloading opAssign in addition to defining postblit. Making assumptions about state of object on entering postblit and opAssign is very risky, you can effectively receive garbage. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
