Metatable inheritance

[Joe Krahn <jkrahn@...>]

I'm new to Lua, so maybe there is already something like this.

If I make my own Lua objects with several Metatable entries, my 
understanding is that I will have to add these entries for every object. 
If I have a lot of these object, that seems wasteful, and adds overhead 
from extra memory accesses. I was thinking, how about having a metatable 
entry called "__inherit", which is just a reference to another table, 
and which is checked if a given entry is not found?
