I use perl since at least 1989 if I judge by some of my advocacy postings. But I can't find perl code written by me before 1991 when I did post to soc.culture.french a script that listed all the words including all the vowels from a French dictionnary. It deals with diacritic characters:

perl -e 'while(<>) {
   if(m/y/&&m/u/&&m/o/&&m/i/&&m/a/&&m/e/){ s/'\''`//;push(@a,$_);}
}
print sort{length($a)<=>length($b)||$a cmp $b;}@a'
 

It was posted as a one liner but I broke it in many lines because I hate code that obliges you to horizontally scroll a page. Today, I would use modifiers and drop parenthesis here and there but would not write it very differently.
