I think the point is getting lost in a loop here... In my opinion, for
__tostring not to be honoured by lua_tostring() is an annoying
inconsistency. It sounds like you're saying the reason for that is
that __tostring is only used by tostring() - i.e. the very
inconsistency I'm referring to? Why can't it be a core metamethod, if
that's necessary for it to work like the others?
