hkaiser: Can you please explain what is the basic use of rebind_pack in datapar traits?
Here https://github.com/STEllAR-GROUP/hpx/blob/master/libs/parallelism/algorithms/include/hpx/parallel/datapar/iterator_helpers.hpp in Line 237 `value_type` is created from iterator’s value type.
In Line 240 we are creating a vector_type `V` which holds value_type.
Then again in Line 254 why do we need to pass `value_type` to `traits::vector_pack_load<V, value_type>`
which internally calls rebind_pack?, why can I use just do load and store operations without rebind pack? because V is already of type value_type why do I need to again rebind with same type?
