So I can load external code which can't modify anything else but
itself.

But how can I prevent the code from reading all files?
Docs say only "Can't load a file from a world-writable directory."

And how can I remove any function I do not want from the wrapping
environment while I for myself am still able to use them?

Or is already done by using anonymous modules? If yes, how? I couldn't
understand this :(

thanks!
