The code I use looks like this: 

my @opts= qw( This That TheOther Else Foo Bar Blatz );
my %opts;
@opts{@opts}= 1x@opts;

sub GetOptions
{
    my $self= shift(@_);
    my $href= {};
    $href= shift(@_)   if  @_  &&  UNIVERSAL::isa($_[0],"HASH");
    @_= @opts   if  ! @_;
    foreach my $opt (  @_  ) {
        croak ref($self),"->GetOptions:  Invalid option ($opt) ",
            "not one of ( @opts )"   unless  $opts{$opt};
        $href->{$opt}= $self->Get($opt);
    }
    return @{$href}{@_};
}

except that %opts actually contains references to "get" methods.

For your helper code I suggest this change: 

sub _populate_hash
{
 my $hvHash= shift(@_);
 my $avValues= shift(@_);
 my $avNames= shift(@_);
 croak unless @$avValues == @$avNames;
 @{$hvHash}{@$avNames}= @$avValues;
}

or just use a hash slice directly in the caller.
