Paul Backus <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Paul Backus <[email protected]> --- Simplified example: --- void main() { Derived d; A a; d.fun(a); } struct A {} struct B {} struct C {} class Base { void fun(A a) {} void fun(C c) {} } class Derived : Base { // if you comment this it will call Base.fun(A) void fun(B b) {} } --- I think what's happening here is that Base.fun and Derived.fun are in separate overload sets, and the derived-class overload set shadows the base-class one. Examining the overload sets with reflection appears to support this hypothesis: --- struct A {} struct B {} struct C {} class Base { void fun(A a) {} void fun(C c) {} } class Derived1 : Base { // if you comment this it will call Base.fun(A) void fun(B b) {} } // prints: tuple(fun) pragma(msg, __traits(getOverloads, Derived1, "fun")); class Derived2 : Base {} // prints tuple(fun, fun) pragma(msg, __traits(getOverloads, Derived2, "fun")); --- --
