Re: multi-level inheritance and __index

[Mark Hamburg <mhamburg.ml@...>]

While one can chain __index accesses, in my experience, it doesn't work particularly well if you want to do anything more than lookup a value. __index is more like a delegation link than it is like an inheritance link.

As a result, I tend toward having no "runtime" dependencies between subclasses and superclasses. (The last class system I built had no inheritance support though it did provide for mixins at class construction time.)
