VERSION

       version 0.53

SYNOPSIS

        use SHARYANTO::Hash::Util qw(rename_key);
        my %h = (a=>1, b=>2);
        rename_key(\%h, "a", "alpha"); # %h = (alpha=>1, b=>2)

FUNCTIONS

   rename_key(\%hash, $old_key, $new_key)
       Rename key. This is basically $hash{$new_key} = delete $hash{$old_key} with a couple of additional
       checks. It is a shortcut for:

        die unless exists $hash{$old_key};
        die if     exists $hash{$new_key};
        $hash{$new_key} = delete $hash{$old_key};

       None are exported by default, but they are exportable.
