very good point. -> true

since I got your attention.. I thing it is time to start a std.container 
discussion. Your AA lib call is not making much progress and I further 
think Steven is also waiting for some D2 decisions.

guess what I want to say is that we need some clarification about ranges 
and opXXX

FI your AA implementation is using ranges as formalism. In other words 
you implement them as part of a node structure. Andrei is defining them 
as Interfaces. Steven also has a different view on how to implement 
collection ( using a struct pair) instead of K,V.  using kinda Iterators..

Almost your questions :

allow custom allocators ?
ref or value semantics
specialized quantity allocators for low/high capacity containers.

what I really like in Steven's implementation is support replaceable 
data structures/algorithms..  AAs could be based on RB trees as well as 
on SkipList..  but : Is this a good thing ? Is there a way to decide at 
runtime ?

In case that we choose classes (implementing Tange Interfaces) it would 
be (IMO) a good start to create the class-interface hierarchy  Andrei 
has an eye on Gobo Eiffel but a discussion would make sense.

a lot of questions, hope YOU will create a new thread.
