code: @Nonnull
  	public static <R> LBiCharFunction<R> biCharFunctionFrom(Consumer<LBiCharFunctionBuilder<R>> buildingFunction) {
  		LBiCharFunctionBuilder builder = new LBiCharFunctionBuilder();
  		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.
