[Boost-users] [range] Tuple initialization?

Subject: [Boost-users] [range] Tuple initialization?

I have a following fragment of code:

        local = boost::begin(f(*current));
        local_end = boost::end(f(*current));

local and local_end are two iterators, f is a function that returns a
range, and current is some iterator I have around. I would like to
initialize two iterators from the range returned by f, but it seems
that I only have two choices: create a local range variable or call f
twice and have two temporary ranges. Am I missing something, or are
these indeed the only choices? Would it be reasonable to have a
begin_end (or such) function that returns a tuple of iterators from a
range for tuple initialization of two iterators? Currently, the range
concepts do not require anything of the sort.

Thanks,
Marcin
