in reply to Why does testing for the existence of hash keys create the keys ?

Could you change the title from being useless to "Understanding creation of missing keys" or similar?

    Point taken about the title ! Thanks all. I had not encountered the term "autovivification" before.

    no autovivification qw(exists);

    should solve my problems without creating new ones !

      Much appreciate the changed title.
