The rest of us find them useful.  Still, BOOST_THROW_EXCEPTION provides a means to configure that, but it affects all Boost code; localizing the effect may be desirable.  Matt called for a differently named container as a means to provide the no-exception behavior.  I think a policy class, defaulted to the throwing behavior, is the better approach, despite Jeff's thinking it an unnecessary complication.

Is it a logic error or a runtime error? IMO exceeding the capacity
here is a logic error and should be handled with an assert by default.
Isn't it comparable to doing a pop_back() on an empty vector?
