__index and __newindex

[Alexander Gladysh <agladysh@...>]

Hi, list!

I often see that people do miss the fact that __index and __newindex
are called for non-existant keys only. When I was a newbie I missed
that too.

Maybe it is a good idea to emphasize this fact in the manual? Like add
a short sentence to the blob of code that now describes the metamethod
behaviour.

I would even go further and add a full natural language description to
each metamethod. While a blob of code is sufficient, it is too formal
for newbie (who is not necessarily verse enough in Lua to get a full
grasp of it).

Alexander.
