           Summary: [DIP1000] return scope wrongly rewritten for structs
                    with no indirections
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: Ajieskola@gmail.com

Compile with dmd 2.100.0 and -preview=dip1000 switch.

---------------
struct Ptr
{ @safe int* fun() return scope {return null;}
  //int* aRef; uncomment to compile
}

@safe int* use()
{ Ptr ptr;
  return ptr.fun;
}
---------------

The compiler detects that Ptr has no indirections, so it correctly judges `return scope` as needless. However, instead of just removing it, it replaces it with `return` attribute. This makes this code to wrongly fail to compile.
