I think we could validate that
columns
is a list of{:list, any()}
. Does it return error if we pass a column that is not a list?There was a problem hiding this comment.

It just silently ignores the non-list columns and the operation is successful. Do you think we should raise on the Elixir side in this case?

@costaraphael personally I think it should raise if one of the columns is not of a list dtype.

@philss @josevalim done in a1ad581!
Since it seems like this is the first time this kind of validation is performed at the
DataFrame
level (checking if the given columns are of a certain type), I've chosen not to introduce any new abstractions. I figured this could be done once there were a couple more examples of this. Let me know if you disagree!
