Hi there,

I'm trying to develop a package DATASTORE used like this

$D = new DATASTORE 'dir', 'filename';
while($_ = $D->getline) {
  [...]
}

[download]

The added benefit of using DATASTORE (in case you're wondering) is that it does some work towards automatically locating the data files I want based on some local config. I'd like the $D variable to inherit all the methods from IO::File.

package DATASTORE;
use parent 'IO::File';

sub new {
    my ($class, @args) = @_;
    my $filename;

    [...]

    $self = $class->SUPER::new($filename, 'r');
    return $self if defined $self;
}

That seems to work for me. Now what I'm not sure about is how you'd adapt the code so that depending on the extension, it uses IO::File OR IO::Uncompress::Gunzip (if the extension is GZ).

Would this be something that's easy to do?
