Currently it isn't possible, but because every page is running in it's own
namespace and Embperl cleans up all your variables after the request, it
isn't such a problem. It's more a problem of programming style. Anyway the
next release of Embperl (not the next beta, but one of the nexts), will
solve this problem.
