 All methods ending in \isa{tac} take an optional first argument that
 specifies the range of subgoals they are applied to, where \isa{{\isacharbrackleft}{\isacharbang}{\isacharbrackright}} means
-all subgoals, i.e.\ \isa{{\isacharbrackleft}\isadigit{1}{\isacharminus}\isadigit{3}{\isacharbrackright}} in our case. Individual subgoal numbers,

 This proof may look surprisingly straightforward. However, note that this
 comes at a cost: the proof script is unreadable because the intermediate
