    $sql->as_sql; # 'foo.id=?'
    $sql->bind;   # qw/1/
    $sql->and('foo.name=?','nekokak');
    $sql->as_sql; # 'foo.id=? AND foo.name=?'
    $sql->bind;   # qw/1 nekokak/
    $sql->as_sql; # 'foo.id=? AND foo.name=?'
    
    my $other_cond = sql_obj('foo.id=?', 2);
    $other_cond->and('foo.name=?','tokuhirom');
    $other_cond->as_sql; # 'foo.id=? AND foo.name=?'
    
    $sql = $sql | $other_cond; # $sql->compose_or($other_cond)
    $sql->as_sql; # ('foo.id=? AND foo.name=?') OR ('foo.id=? AND foo.name=?')
    $sql->bind;   # qw/1 nekokak 2 tokuhirom/

    $sql->add_parens;
    $sql = $sql & sql('baz.name=?','lestrrat'); # $sql->compose_and(sql('baz.name=?','lestrrat'))
