It happens to work because that happens to be how Sessions are implemented
this week.
Programming 101:
Rule #27: Relying on implementation minutia instead of documented functions
is just a Bad Idea (tm).
Use the functions that are documented to work. Anything else is a HACK and
subject to break without notice.
In PHP 4.3 or 5.0 or 7.3.1, when it *DOESN'T* work anymore and you have a
zillion lines of code cramming junk into $_SESSION scattered all through
your application, don't come crying to me. :-)
