I think that DataArray{Any, 1} is probably the best thing you could possibly do.
But it’s still going to cause people lots of problems, because there’s almost
never a time when you’d want to work with DataArray{Any, 1}.
At some point, we have to improve the @data macro.
But for this use case, I suspect people are much better off using
DataArray(Float64, 1)
or something similar to produce an all-NA array of type T and size S.
