Bug 8265 – UFCS fails when called across modules

// File: main.d module main; import test; struct MyStruct { int _value; int memberGetValue() { return _value; } } int nonMemberGetValue(MyStruct ms) { return ms._value; } int main(string[] argv) { static assert(test.memberTest(MyStruct(42))); // #0: OK static assert(MyStruct(42).nonMemberGetValue() == 42); // #1: OK static assert(test.nonMemberTest(MyStruct(42))); // #2 return 0; } //... // File: test.d module test; bool memberTest(T)(T t) { return t.memberGetValue() == 42; } bool nonMemberTest(T)(T t) { return t.nonMemberGetValue() == 42; // #3 } // #2: Error: template instance test.nonMemberTest!(MyStruct) // error instantiating // #3: Error: undefined identifier 'nonMemberGetValue'
