CachingPool-like object that caches objects instead of closures?

General Usage

From what I can tell, CachingPool caches things at the level of the closure, so if you have multiple closures using the same “big” object, it gets sent twice. E.g.

function foo(pool)
    dat = BigObject(...)
    pmap(workers()) do i
        something(dat)
    end
    pmap(workers()) do i
        something_else(dat)
    end
end

pool = CachingPool(workers())
foo(pool) # dat will be sent twice

Does anything exist that would cache at the level of the object, so that dat is only sent once? I’m aware that auto-global-shipping would work, but is there a solution that doesn’t rely on a global state?
