Re: what do you call this data structure?

    $c is a reference to a hash of arrays. Refer to perldsc.

    To use slightly-more Perlspeak:   “$c is a hashref that refers to a hash containing two keys, even and odd, both of which are arrayrefs that refer to a separate arrays of 4 integers.”

      hashkey can't be arrayrefs, they're hashkeys, they're strings

    I call it incomplete. Where are zero and nine?

      Not necessarily. Let's give the OP the benefit of the doubt and assume that the names make sense in context. (e.g. He is working with eight objects.)

    (The original post here was mine ... PM logged me out.)   My intended meaning was that “the values associated with {each key within the hash} are {arrayrefs} ... etc.”   (Braces added for clarity.)

    But here again, heh..., is potential ambiguity to those who, so to speak, “do not (yet...) speak the language.”   Thanks for the clarification.
