Title
Body
I'm wondering if it's possible to forward declare an enum that's defined within another class scope. For example, consider the following: //A.h class A { public: enum class type: unsigned long { /*some stuff*/ } }; Now, in another header I'd like to forward declare the 'type' enum (suppose class B below has a function that does something with A::type) //B.h enum A::type; //use of undefined type 'A' class B { public: UseTypeEnum(A::Type&); }; This doesn't work either: //B.h class A; enum A::type; //still use of undefined type class B... There's no problem if the enum is declared at global scope in A.h. Is there any way to do this?
