Sorry for any confusion Gaspard, only lua_setfenv() changes the 
environment so you should be fine if you don't call lua_setfenv(). My 
confusion when I last worked with function/userdata environments came 
from the fact that my C functions inherited their environment from the C 
module loader and this surprised me (although it's more or less 
documented) but in retrospect this doesn't seem relevant to your question.
