code: @Nonnull
  	public static <T1, T2, T3, R> LTriFunctionBuilder<T1, T2, T3, R> triFunction(Consumer<LTriFunction<T1, T2, T3, R>> consumer) {
  		return new LTriFunctionBuilder(consumer);
  	}
docs: One of ways of creating builder. This might be the only way (considering all _functional_ builders) that might be utilize to specify generic params only once.
