+1 for a simple rotation feature. Would be super useful!

I think this is related to #115

If one wants to implement this, the non-blocking collectives should be listed here: https://www.mpi-forum.org/docs/mpi-3.1/mpi31-report/node95.htm#Node95. API-level wrappers seem to already be available, e.g. https://github.com/JuliaParallel/MPI.jl/blob/1b9ce103b65090cc1c9a5a213262424f65dca003/src/api/generated_api.jl#L593-L595 Hence, it seems one would only need...

It is your call and it's fair enough to not create a test directory. :) > That is very much true, but the target of DrWatson is good scientific practice...

This should be solved by https://github.com/JuliaLang/AllocCheck.jl, right?

Alright, I've dropped the copying definitions and restricted the introduced `Bcast` to `isbitstype`s where we can just wrap the object into a `Ref`. This still removes the ugly manual wrapping/unwrapping...
