On the topic of strange behaviour wrt. environments...
I was more than a little surprised to find that while
GETGLOBAL/SETGLOBAL opcodes use the environment, the lua_getglobal and
lua_setglobal macros use LUA_GLOBALSINDEX rather than LUA_ENVIRONINDEX.
Is this deliberate, should I be using LUA_ENVIRONINDEX explicitly?
Confusedly yours...
