digitalmars.D.bugs - [Issue 19652] New: [REG2.084] alias this chain no longer works


          Issue ID: 19652
           Summary: [REG2.084] alias this chain no longer works
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: johanengelen weka.io

The following code used to compile but no longer does with dmd 2.084:
struct Base {
    int i;

struct A {
    Base base;
    alias base this;

struct B {
    A a;
    alias a this;

auto asGeneric(inout ref Base block)  nogc {
    return █

B* thingie;
auto foo() {
    return asGeneric(*thingie);

Error: `cast(Base)(*thingie).a` is not an lvalue and cannot be modified
