+1 I even agree with @stevengj's original point: those who need `malloc` dirty memory can just use `ccall`.
If we can make this work without performance degradation, I'm in.
Adding units should be trivial, especially if Julia settles on a standard unit package soon. What are the variable labels for: descriptions of the columns to supplement the brief names?
I think separating Likert scales from other categorical variables might be too specific for something as generic as DataFrames: what functions would apply to them that don't apply to other...
You could actually do that already: you'd just make a `DataArray{LikertResponse}`, where `LikertResponse` is a custom type. This is one of the virtues of our approach to `NA`: you can...
What would arbitrary metadata consist of? A Dict called metadata that people can do anything with?
If you're up for making a demo with that approach, it'd be nice to see. My instinct is that trying to avoid pre-specified types is going to make things slow,...
Here's the metadata I'm on board with adding permanently: - Nullable: Is this column a Vector or a DataVector? (Note that, if we make the changes described in a recent...
