code: @Nonnull
  	public static <T1, T2> LToIntBiFunctionBuilder<T1, T2> toIntBiFunction(Consumer<LToIntBiFunction<T1, T2>> consumer) {
  		return new LToIntBiFunctionBuilder(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.
