in reply to Concerning hash operations (appending, concatenating)

Duh, just use array_merge from "Array-PAT", which I've reproduced below for your convience:
sub array_merge{ my(@array1, @array2) = @_; foreach my $element (@array2){ @array1 = (@array1, $element); }#foreach return @array1; }#array_merge

    Is this a joke BUU?

    Lets have a look at the code:

    my(@array1, @array2) = @_;

    So this line will magically split @_ into two parts, the first part will go into @array1 and contain the whole contents of @_, @array2 will be empty.

    foreach my $element (@array2){ @array1 = (@array1, $element); }#foreach

    Good thing this loop never executes as its a pretty inefficient way to add elements to an array. Perhaps the author has never heard of push.

    So this entire subroutine could be replaced by:

    sub array_merge{ @_ };

      Of course it's a joke.

      Good lord.
      Wow, that's actual code checked into CPAN.

      I guess it does what it says it does, anyways, just has some code that's never used.

      I guess I don't understand what it has to do with concatenating hashes??
      "But what of all those sweet words you spoke in private?"
      "Oh that's just what we call pillow talk, baby, that's all."
        Well, since hashes can be listified, you could use this to merge two lists that just happen to be hashes. And yes it's utterly pointless.
