Re: [boost] Adding 'indirect_sort' to boost::algorithm

So you are adding a building block to have such a "cosort". You're just missing a way to apply that reordering to several (random-access) collections.

There already is: Basically you first do an indirect sort and then use `boost::algorithm::apply_permutation` on each collection with the result permutation. See the test case and documentation of indirect_sort. Alex
