Do you mean simply that:
':method' would be a syntax shortcut for 'self:method'
And
'.field' would be a syntax shortcut for 'self.field'
?
Beyond that you are opening a (very familiar) can of worms. Lua does not
have the concept of 'class' and this concept can be implemented in many
different ways, so 'classname' could be a table or a userdata or in my
personal favourite style, a function closure. So there is no determinate
lexical context for a class - it all depends how you want to implement it.
