classes

I don't really like the way Lua implements classes.  The difference between ":" and "." is confusing and the use of advanced features like setmetatable and __index don't seem necessary.  Here is how I would implement the examples in the "Programming in Lua" book:

oo.lua

Note that this works fine in Lua as it is.  If you think this is good enough, then I won't implement the ":" operator.

Sounds good to me. This is another example of a feature that can be improved later without harming previous code. Also, I am still not sure how much Nabble will rely on classes, so I think we can keep it simple for now. But what about metamethods like __index, __add, __div, etc.? Do you plan to skip them too?

I am implementing metamethods now.

Okay, back to you.
