http://d.puremagic.com/issues/show_bug.cgi?id=5187 Summary: Attribute hiding error or warning Product: D Version: D2 Platform: All OS/Version: All Status: NEW Keywords: diagnostic Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: bearophile_hugs eml.cc This D code gives no compilation errors with DMD 2.050: public class Foo { public int x = 10; } public class Test : Foo { public int x = 20; } void main() {} public class Foo { public int x = 10; } public class Test : Foo { public int x = 20; // warning public static void Main() {} } warning CS0108: `Test.x' hides inherited member `Foo.x'. Use the new keyword if hiding was intended public class Foo { public int x = 10; } public class Test : Foo { new public int x = 20; // OK public static void Main() {} } A similar error (or warning), with a similar "new" keyword solution, may be added to D, so unwanted hiding of attributes may be avoided. This is related to using the obligatory "override" keyword: bug 3836 And this warning that I think is better to become an error ASAP: bug 4216 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
