local vs global?

[PA <petite.abeille@...>]

Hello,

Now that I'm getting up to speed with Lua, I find the default behavior 
of assigning everything to the global environment quite disconcerting. 
It seems to me to be a case of "think locally, act globally". I would 
much more prefer the reverse: "think globally, act locally".

I'm aware of the setfenv() function, but this require a fair amount of 
hand holding, is too error prone for my taste as well as fairly obscure 
all things being equal.

What I would like to setup is something along the following lines:

- By default, things are always 'local' to the file (package) they are 
declared in.
- If I want to export them to the 'global' name space I have to do so 
explicitly: "global MyGlobalStuff".
- Everything has to be either "local" or "global". No loose ends.

What would be a straightforward way to setup my Lua environment to 
achieve the above goals?

TIA :)

Cheers
