Not being the original developer I cannot give you an answer. But if you
have code which you feel should work, please create a PR. You could
alternately add a Boost trac item for your suggestion.

I have updated the iostream doc on the 'develop' branch regarding this
but will wait for 1.64 release. Thanks for pointing it out.
