Hi,

thanks for looking at this.

Perhaps, but Jeremy's patch prevents that any proxy based iterator can be an output_iterator. This is why I'm asking for help understanding the output_iterator requirements. I don't think that MultiArray has any chance of avoiding the proxy. What also strikes me as odd about Jeremy's patch is that it makes "iterator_writability_disabled" completly unused, yet doesn't removes it or updates the documentation of iterator_facade_default_category.
