Hmm. Here's an extremely condensed (not exhaustive) summary of changes, future directions and open issues.
Off topic:
It isn't off topic, I guess :)
what is your opinion on being able to use negative indexes in operator[]?
Just for the case index == -1 or in general?
Like bs[-1] would return the last value stored? (Or with different syntax bs[boost.end - 1].)
So that, in general, b[i] with i<0 would give: b[sz - ((-i) % sz)] where sz = b.size()? [Note that this gives undefined behavior when the absolute value of i is a multiple of sz] Is there a motivating case for this? My fear is that it slows down operator[].
Such feature has been asked for with circular_buffer.
Could you please point me to a post that describes the semantics? I'm not following the circular_buffer review, unfortunately. Thanks, Genny.
