            Bug ID: 16612
           Summary: Type diffing should highlight reference/pointer-ness
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dblaikie at gmail.com

    Classification: Unclassified

Given:

template<typename T>
class foo {
};

void func(foo<int>);

int main() {
  foo<int*> f;
  func(f);
}

(or similarly, with foo<int&>) template type diffing highlights the whole of
"int*" and "int" as being different - it'd be useful if it drew attention to
the "*" being the important difference. With longer/larger types it can be
difficult to notice that it's just a matter of passing a pointer versus passing
a value.
