          Issue ID: 24627
           Summary: Disallow qualifiers as member function attributes in
                    prefix notation
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: qs.il.paperinik at gmail.com

Issue 4070 was rejected on the grounds of symmetry. My sense is that Walter’s
objections are invalid. There is precedent for asymmetry on function
declarations:
`ref` prefix-only.

Worse, `ref const int f() { }` really, really looks like `const` applies to the
return type.

If breakage is deemed too much, this can be done in the next edition of D
(assuming editions are being implemented). All prefix type constructors should
be applied to the return type. Everything that affects the function (or
function type) or the implicit this goes at the end as a (member) function
attribute.
