34 the first alternative. We need to add some additional rules allowing to make the
35 first alternative fail. So, if the first alternative fails the second one will 
36 be chosen instead. The decision about whether to choose the first alternative

173 happens for instance in alternative generators, where some of the alternatives
174 need to extract only part of the overall attribute passed to the alternative
189 complex number is equal to zero or not. The first alternative is executed if the 
190 imaginary part is not zero, the second alternative otherwise. This time we make

213 alternative is `tuple<double, double, double>`, we need to skip the first and
