The above proposal doesn't really fix things (it does improve things
somewhat). I think a full solution should control all global access not
just creation.
This idea doesn't add anything to the language (it adds to the C code).
What is the solution that doesn't require changing Lua? Didn't I go into
the need to optionally enforce some scheme (since anything else is to some
degree like saying, "practice good programming")? I hope these notes are
actually getting through.
Does anyone know how to make the list server send emails to the sender?
I'm not getting copies of my own emails.
