http://d.puremagic.com/issues/show_bug.cgi?id=3265 Summary: Interface-typed function parameter does not return instance's ClassInfo Product: D Version: 2.031 Platform: All OS/Version: All Status: NEW Keywords: spec, wrong-code Severity: major Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: hskwk inter7.jp If function parameter type is a interface, parameter.classinfo returns inteface's ClassInfo instead of instance's ClassInfo. interface I {} class C : I {} class D : C {} void o(in Object obj) { writeln(obj.classinfo.name); } void i(in I obj) { writeln(obj.classinfo.name); } void c(in C obj) { writeln(obj.classinfo.name); } void main() { auto d = new D; o(d); // -> D i(d); // -> I, wrong c(d); // -> D } I suppose this behavior is a bug. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=3265 --- It is not related to function argument. This bug occured by interface reference. Sorry for rough information. interface I {} class C : I {} class D : C {} void main() { auto d = new D; C c = d; writeln(c.classinfo.name); I i = d; writeln(i.classinfo.name); Object o = d; writeln(o.classinfo.name); } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

It sound true so that I changed the issue as not important. I suggest that at least this spec should be documented. This behavior is very confusing, I suppose it is better to replace classinfo property from interface reference by other appropriate way. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
