With a little help from you friendly neighbour CPAN modules this is a pretty standard plugin loader 
use Carp           'croak';
use Module::Locate 'locate';

sub get_a_parser {
  my $mod = "EP::Parser::$_[0]";
  require locate $mod
    or croak "Couldn't locate module '$mod'";
  return $mod->new( @_[ 1 .. $#_ ] );
}
