Empty tuple in an interface's base type list should be legal as it is with
classes.
import std.typetuple;
interface I {} // ok
interface I2 : TypeTuple!() {} // ok
interface I3 : TypeTuple!(I) {} // ok
class A : I, TypeTuple!() {} // ok
interface I4 : I, TypeTuple!() {} // fail
Error: interface a.I4 base type must be interface, not ()
