Warning on it would create too many spurious warnings. This check belongs in linters (e.g. perlcritic). If \E is found but there was no active \Q \l \u \L \U then warn. > \u and \l have nothing to do with \E, but warning on \E if there's no \Q, \L or \U in effect sounds appropriate to me. - EricThread Previous | Thread Next
