primarily, global variables are looked down upon.
but like the error message says, you can explicitly name any
global like this:
$The::Meaning::Of::Life::The::Universe::And::Everything = 42;
you might also try
use vars($Something);
$Something = &whatever();
but you should probably use closures and references instead.
(i'll be re-coding my website to avoid globals in the next
few weeks, now that i understand what i just said, there. :)
