Here is the idea. For code like this it would be very helpful to report
suggestion about turning a field into constant.

class C
{
 static BindingFlags b = BindingFlags.Public | BindingFlags.NonPublic;

 static void Foo ()
 {
    BindingFlags b2 = b | BindingFlags.IgnoreCase;
 }
}


Basically anytime when a primitive type or enum are read only they can be
turned into a constant. There are some exceptions but I generally this should
be quite easy to implement ;-)

I think this rule can apply to both class/struct fields and local variables.
