This is because UNIVERSAL::VERSION() looks up the packages $VERSION
variable at runtime using hv_fetchs(pkg, "VERSION", FALSE).

These, on the other hand, were bound at compile time, and don't go
through the symbol table at runtime. This is how e.g. namespace::clean
can remove imported functions from the symbol table at the end of
compilation, so they can't be called as methods.
If you wrap the before-unload tests, the unload call and the
after-unload tests in separate BEGIN blocks, you'll see the results
you're expecting.
