Bug 21812 – __traits(allMembers) on types with value tuples return ghost members

Consider the following code: ----- struct S(A...) { A args; } void main() { pragma(msg, __traits(allMembers, S!(int, float))); } ---- This outputs the following: tuple("args", "__args_field_0", "__args_field_1") The members __args_field_0 and __args_field_1 don't exist on the type: --- S!(int, float) s; // all of these produce the error: no property __args_field_0 for type S!(int, float) writeln(s.__args_field_0); writeln(__traits(getMember, s, "__args_field_0")); pragma(msg, __traits(identifier, __traits(getMember, typeof(s), "__args_field_0"))); --- I would contend that __traits(allMembers) should not ever return strings that are not accessible in any way as a member.
