To the best of my knowledge, only CodeWarrior was specifically  
designed to accommodate such use cases.  It is an issue that has been  
discussed at the lwg level now and then, especially in the context of  
what to do about vector<bool>.  My personal feeling is that we should  
attack vector<bool> on two fronts (speaking from a standards point of  
view here):

1.  Get rid of it (probably deprecating first) but at the same time  
supply the equivalent functionality (e.g. bitvector).
2.  Make the std::lib more friendly towards proxied iterators so that  
bitvector and containers like it have better interoperability.   
Exactly how to do this hasn't been discussed in much detail, except  
in isolated cases such as

http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#307

which does not address our issue specifically, but is only related in  
by point 2 (make std::lib more friendly).
