I personally think the criticism of __index/__newindex & __len
metamethod functions is valid.

I don't understand why the '#' syntax does not use the __len metamethod
function for tables when it is respected elsewhere. The only thing I can
think of is that there might be some bad code elsewhere it might break
or that the "original developers" simply overlooked it.

The __index/__newindex method thing I can actually understand, on the
other hand - I would like to see the __useindex metamethod patch from
the "Lua Power Patches" investigated. The only reason I don't use it at
the moment is it breaks LuaJIT, and the only reason I haven't whined
about that is I know Mike is working on a new LuaJIT...
