Comment by Sidharth Juyal (JIRA) This issue is described here: https://stackoverflow.com/q/55186648/286094 IMO this is not a programmer bug, I would expect it should just work as desired as in case of other languages like C++ struct CommonField {
std::string name;
CommonField(const std::string &name) : name(name) {}
};
struct Base {
struct Field : public CommonField {
Field(const std::string &name) : CommonField(name) {}
};
};
struct Derived: public Base {
struct Field : public CommonField {
Field(const std::string &name) : CommonField(name) {}
};
};
void run()
{
auto a = CommonField("field");
auto b = Base::Field("base.field");
auto c = Derived::Field("derived.field");

Yeah, I think this is shadowing, not redeclaration. We don't treat it as shadowing today, though. |
