What's wrong with upvalues?

In 5.1, CFunctions will have an environment table just like Lua 
functions. So that could be assigned to the package table. (In fact, I 
think the 5.1 loadlib system does exactly that. It certainly seems to 
have a dynamic unloading __gc method, at least on some OS's.)

But I'm still not convinced that unloading dynamic modules is a good 
idea.
