-So, you would like to have to write
-        switch(var)
-           {
-           case foo: fallthrough;
-           case bar: fallthrough;
-           case baz: fallthrough;
-           case mung: /* code to do something for all four cases */
-           }

While this would work, if we assume D has aggregate constructors,
there is a handsomer way:

	switch (e) {
	case [1, 2, 3, 5, 7, 13, 19, 23]: ...
	}
	/* syntax above is only for demonstration */
