How would I change my current environment in lua?

[LuaTenshi]

So when I was working on this...

/index.php/topic,6987.0.html#msg34775 />
I got a message saying this...

dont do it on g
do it on the current environment
make a new environment

So how exactly would I even start doing that, I am currently pretty tired so sorry if I am just being stupid but I have checked all of the following sites, and I am still not sure how to do it.

Any table is its own environment. This person is just saying to do it on a table. E.G., do plys, then you can go plys.Megiddo (or whatever).

Tbanks, I wish that this information was easier to get... :\
