Interfaces can have const fields, which are implicitly static. They can have
static fields that are not const.

Let's take this example (from ANTLR):
interface Token
{
   const int EOF = -1;
   static Token EOF_TOKEN;
   static this ()
   {
      EOF_TOKEN = new CommonToken(EOF);
   }
}

This produces an error saying that _staticCtor1 is not abstract.

The workaround is to move the static constructor out of the interface. This is
not problematic; it is merely inconsistent.
