in reply to Override exists()?

exists should not return the value for the specified key; it should always return true if there is such a KEY (the value may be undefined or false).

Why don't you just return a true value for EXISTS and a list (or array-ref) of matches for FETCH?

    I tried that, too, in the time since I posted: 
      my @x = $hash{$key};

    But inside the code, wantarray is not set. I suppose I could just return a listref, but ... I'm stubborn.
