Strange indeed. I copied the patch a few days ago from the Wiki page and
I did change the error() line to a print(). But that shouldn't change
the env[name] to a rawget() unless there was magic in the air.
As to the many-modules-in-a-single-library-file problem, I'll stick with
my own solution. However, checkglobals() is a handy tool for checking
programs. Thanks for dreaming it up.
And perhaps, in a few years' time, the Gods will hand down full globals
and a nil that's not a nil.
