P-Stade Oven range library provides many useful range adaptors.
For your use case, you can use more generic `pstade::oven::elements_c<N>`
range range adaptor (or `pstade::oven::make_elements_c<N>`)

    *boost::find_if(rng | pstade::oven::elements_c<0>(), pred) = val;
    *boost::find_if(pstade::oven::make_elements_c<0>(rng), pred) = val;

Here is the documentation:
    http://p-stade.sourceforge.net/oven/doc/html/oven/range_adaptors.html#oven.range_adaptors.elements_c
See also:

If you use clang and libc++, you might have a compile error due to the
incompatibility between the forward declaration and the inline namespace.
In that case, you can fix the problem by removing the forward declaration of
`std::pair` and adding `#include <utility>` in pstade/apple/pair_fwd.hpp.
