DBD::Gofer middleware thoughts (was Idea for a Gofer transport for translating SQL - primarily intended for testing)

If we have a DBD::Gofer middleware feature then it would be helpful to 
add a new passthrough (or "passthru") transport.  This would be based on 
the null transport, but without the serialization/deserialization, i.e. 
something as simple as:

    package DBD::Gofer::Transport::passthrough;

    #

    use strict;
    use warnings;

    use base qw(DBD::Gofer::Transport::Base);

    use DBI::Gofer::Execute;

    our $VERSION = sprintf("0.%06d", q$Revision: 10087 $ =~ /(\d+)/o);

    my $executor = DBI::Gofer::Execute->new();

    sub transmit_request_by_transport {
        my ($self, $request) = @_;
                                                                                                                                                    

        return $executor->execute_request( $request );
    }

    1;

This would be suitable for middleware modules to wrap.
