__index and __newindex are only called if the corresponding table
entry doesn't exist (i.e. is nil). As soon as a non-nil value
exists for a key, no metamethods are called on reads or writes.

May I suggest you (re)read "Programming in Lua". :-)

Well no, I don't think this is a good idea. First: I wouldn't
bother with lazy loading -- libcurl doesn't have that many
symbols. And second: I cannot see any reason why a user of a
library would behave that way and why you go to these lengths
trying to forbid this.

I mean, anyone can write math.sin = math.random -- yeah, that's a
bad idea, but so what? It's the user's problem, if they do such
nonsense.
