Тук имам един въпрос - понеже на много места досега сте казвали да избягваме методи с ! по всякакъв начин затова и тук така съм направил. Но все пак x = x.gsub... ми се струва малко WET в дадения случай и реално не е ли че gsub! прави същото. При това положение правилно ли съм избягвал gsub! или това е един от малкото случаи, когато няма проблем да ползваме метод с ! (ако това се извършва в някакъв tap)?
