           Summary: Missing warning for const conversion operator
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: rafael.espindola at gmail.com

In

class foo  {
public:
  operator int * const ();
  int * const bar();
};


clang produces a nice warning for the second case:

test.cc:4:9: warning: 'const' type qualifier on return type has no effect
      [-Wignored-qualifiers]
  int * const bar();
        ^~~~~

but no warning for the conversion operator. We probably need a slightly
different wording, but it would be nice to have a similar warning for it.
