> Certain applications would benefit from being able to inspect DataFrames that 
> are straightforwardly produced by data sources that stem from files, and find 
> out their source data. For example, one might want to display to a user the 
> size of the data underlying a table, or to copy or mutate it.
> Currently, there is not a good way to get this information in a public API.
