digitalmars.D.bugs - [Issue 19415] New: return non-copyable struct fails if member


          Issue ID: 19415
           Summary: return non-copyable struct fails if member function
                    has return attribute
           Product: D

struct S
   int x;
   S foo() return { return S(x); }
   this(this)  disable;

S bar()
   S s;
   return s; // Error: struct `S` is not copyable because it is annotated with

This fails to compile, unless you comment out the `foo` member. It seems
completely unrelated, as it's never called.

This expectation of being able to return a local as an rvalue is paramount
inside std.algorithm.move.
