That can be a lot of tables. Usually its OK.
Personally, I wish I could use any lua value as an argument to
lua_setfenv(). It would be easier in simple cases.
I don't understand why lua would care if I used a function object, or
a userdata object. Unlike the fenv of a function, its
not used by lua, just by my code.
