Spin-off compiler regression from: https://d.puremagic.com/issues/show_bug.cgi?id=12000#c1 struct RefCounted(T) { struct RefCountedStore { private struct Impl // line 5 { SharedInput _payload; } private void initialize(A...)(auto ref A args) { import core.memory; } void ensureInitialized() { initialize(); } } RefCountedStore _refCounted; void opAssign(SharedInput rhs) { } int refCountedPayload() { _refCounted.ensureInitialized(); return 0; } int refCountedPayload() inout; alias refCountedPayload this; } struct SharedInput { Group unused; } struct Group { RefCounted!SharedInput _allGroups; // line 45 } void main() {} Output: test.d(5): Error: struct test.RefCounted!(SharedInput).RefCounted.RefCountedStore.Impl unable to resolve forward reference in definition test.d(45): Error: template instance test.RefCounted!(SharedInput) error instantiating
