code: @Nonnull
  	public static <T1, T2, R> LObjIntObjFunction<T1, T2, R> objIntObjFunctionFrom(Consumer<LObjIntObjFunctionBuilder<T1, T2, R>> buildingFunction) {
  		LObjIntObjFunctionBuilder builder = new LObjIntObjFunctionBuilder();
  		buildingFunction.accept(builder);
  		return builder.build();
  	}
docs: One of ways of creating builder. This is possibly the least verbose way where compiler should be able to guess the generic parameters.
