Re: [boost] [range] adaptors vs. rvalue to lvalue& binding

Back to your function - perhaps taking unqualified template parameter is not the best idea, and if you want to take a range you might want to be bit more explicit about it? E.g. like this:

template<typename T1, typename T2> void modifies_range(boost::joined_range<T1, T2> && rng);

I hope users of such "modifies_range" function would find nothing to complain about such an interface.

Unfortunately, the reference collapsing no longer works in this case, so this function will not accept an lvalue joined_range. Regards, Nate
