true. We can refer to a faq, one with a hack or two.

Some really want it, let's define the most efficient/least ugly types of
hacks :) For example with get, checking phpversion, then appropriatly
defining $_GET = &$HTTP_GET_VARS. And in a function, do: global $_GET. Now
mimicking $_SESSION functionality is another story, eww, maybe that's
going too far.

Regarding the extract() idea, please clarify a little more.
