Re: Getting pair of values from an array

Your second example is on track: treat @_ as a hash.

sub newfoo {
        my %hash = @_;
        foreach (keys %hash) {print "$_: $hash{$_}\n";}
}

When you use an array as a hash, it is automatically broken up into key, value pairs.

...treat @_ as a hash. You are not TREATING the array as a hash, but in fact COPYING its contents into one. As noted elsewhere by Screamer, using a hash ignores the potential data loss of duplicate keys in the data. `splice()` is the way to go. dmm You can give a man a fish and feed him for a day ...
