This should now be possible https://github.com/JuliaIO/JLD2.jl/issues/57

I have suggested that Checkpoints.jl's `checkpoint` function should do the opposite that function is both similar and different. https://github.com/invenia/Checkpoints.jl/issues/16

Safe and General to arbitary types is impossible AFAICT. Every package that accepts reading arbitary types eventually falls back to the julia serializer, or internal code that is behind the...

Answer: ``` by(Impute.locf!, deepcopy(df), :unit) ``` One does not want to individually `deepcopy` each group (which is what `lcof` does), because each group has a reference to the partent dataframe,...

In this case that `by` expression does not depend on whether `Impute.locf!` is inplace or not.

My point was: `by` appends all `AbstractDataFrames` that are returned. So it is certain to work. Regardless of if mutating or not. As you say, the reason to use `lcof!`...

maybe we should do less `deepcopy` and more `copy` I suspect everything we want to apply this on has `copy` defined. Since the whole problem was `deepcopy` on a `GroupedDataFrame`...

I don't see why we are not picking up the global Manifest in this case? Seems like a bug.
