[boost] [foreach] cheap_copy crisis?

Hi,

Under VC++7.1,
I was surprised that a class derived from 'boost::iterator_range'
was almost copied by BOOST_FOREACH.
('boost::noncopyable' works!)

I think such a range that is noncopyable but derived from
iterator_range is valid, isn't it ...?
I think it could be dangerous if users can't find cheap_copy-customization.

Regards,
