Maybe this has changed in the meantime?

mike@honeybadger:~/build/php-unicode-debug$ cli -r 'var_dump(new ResourceBundle("/home/mike/cvs/php-src/ext/unicode/tests/test"), new ResourceBundle("/home/mike/cvs/php-src/ext/unicode/tests/test2"));'
object(ResourceBundle)#1 (4) {
  ["data"]=>
  unicode(5) "value"
  ["greet"]=>
  array(7) {
    ["1%4"]=>
    unicode(13) "Good morning."
    ["1%5"]=>
    unicode(15) "Good afternoon."
    ["1%7"]=>
    unicode(13) "Good evening."
    ["1%8"]=>
    unicode(11) "Good night."
    ["4%14"]=>
    unicode(7) "Please "
    ["4%19"]=>
    unicode(10) "Thank you."
    ["4%20"]=>
    unicode(10) "Sincerely,"
  }
  ["list"]=>
  array(3) {
    ["one"]=>
    int(1)
    ["three"]=>
    string(1) "4"
    ["two"]=>
    unicode(1) "2"
  }
  ["serial"]=>
  array(3) {
    [0]=>
    int(1)
    [1]=>
    int(3)
    [2]=>
    int(5)
  }
}
object(ResourceBundle)#2 (1) {
  ["test"]=>
  unicode(4) "data"
}

It would really sound odd if it would be keyed by the locale only...
