code: @Nonnull
  	public <V1 extends T1, V2 extends T2, V3 extends T3> LTriConsumerBuilder<T1, T2, T3> aCase(Class<V1> argC1, Class<V2> argC2, Class<V3> argC3, LTriConsumer<V1, V2, V3> function) {
  		PartialCase.The pc = partialCaseFactoryMethod((a1, a2, a3) -> (argC1 == null || argC1.isInstance(a1)) && (argC2 == null || argC2.isInstance(a2)) && (argC3 == null || argC3.isInstance(a3)));
  
  		pc.evaluate(function);
  		return self();
  	}
docs: Adds full new case for the argument that are of specific classes (matched by instanceOf, null is a wildcard).
