I used /x in a solution to the 4 Consecutive Letters challenge on FWP in August 2000: perl -ne'for$i(97..119){print,last if/@{[map chr,$i..$i+3]}/x}' (Tim Ayers then reduced this to: perl -ne'@a=a..z;for$i(0..22){print,last if/@a[$i..$i+3]/x}' ) The challenge was to find words which contain four consecutive letters as they appear in the alphabet, i.e. understudy contains rstu.
