Hi,

iterator_range operators are defined like this:

template< class IteratorT, class ForwardRange >
inline bool operator==( const ForwardRange& l,
                        const iterator_range<IteratorT>& r )
{
    return boost::equal( l, r );
}

These needs to be restricted with enable_if on type of first argument.
I have a scenario where I want to define operator== for my own type 
and want to be able to use it with iterator_range as second argument. 
Above definition makes it impossible.
