Well, that conversion still needs to happen somewhere, since plenty of apps call extract() on those superglobals, but with register_globals entirely gone in PHP 6, I suppose that conversion can be moved to the extract() call.

Hi,
I'm not sure it needs to happen anywhere. Such symbols could be simply referred to with the intended syntax: ${'a.b.c.d'}.
By the way, extract now seems to just ignore those vars when given an array:
extract(array('foo.bar' => 'baz'));
echo ${'foo.bar'}; // notice, no such variable
echo $foo_bar; // notice, no such variable
