Re: Accessing container's methods

Annoyingly, there seemed to be no responses to the original question 
when I wrote that and then shortly after, I saw all the others (and we 
all pretty much said the same thing - so I'm not sure why I was singled 
out for special attention ;)).

Fixed(*)

Thomas 'PointerEars', you have chosen to selectively quote snippets of 
code and comments out of context, so I think it's futile to respond to 
those arguments individually. The original request (if you read it) was 
to return a string that said, essentially, "I am element 2 of 3 in my 
container".

You posted a "Quickhack" (which, to be fair, is an accurate description) 
which is incomplete, has errors and makes no sense in the context of the 
original question. We all know we can create a list in Python (of parent 
objects or whatever), but I think that if you expanded on that class a 
bit more (methods for the containers to update the contained objects on 
just what their index/key is etc) that you'll soon realise it's not a 
scalable option.

Also, WRT the original question, what is the method supposed to return 
now? "I am element 0 of 3 in container <FOO>, key 'bar' of ('bar', 
'foo', 'spam') in container <BAR>"? Just curious.

I'm interested in this response though:

Please elucidate. Examples from the standard library would be interesting.

E.

(*) In the sense that it's not going to change ;)
