But global assignment is just a convenience, it provides a sandbox for 
the module, right? If you add a setfenv after the table creation, you 
would get that, right? And if you did that, then you get the 
"convenience" of global assignment. And you can still use 'local 
function' for unexposed functions, couldn't you?
