Re: [boost] operators library

There's a known problem with boost::output_iterator_helper and MSVC, which
chokes on void default template arguments.
The interface to output_iterator_helper needs to be changed anyway, to
remove all of those parameters which default to void (an output iterator
/must/ have void value_type and differnce_type anyway).

Could that be involved somehow?
