code: @Nonnull
  	public <V extends T> LOiToSrtFunctionBuilder<T> aCase(Class<V> argC1, LOiToSrtFunction<V> function) {
  		PartialCaseWithSrtProduct.The pc = partialCaseFactoryMethod((a1, a2) -> (argC1 == null || argC1.isInstance(a1)));
  
  		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).
