I don’t like that this invents new column names when there is a collision. This definitely should not be the default behavior. I would rather throw an error (but I’m not sure that is better than letting the last column win, as Object.assign does).

I think it is better to use parseRows if the column names are not unique.

Then maybe https://github.com/d3/d3-dsv/pull/74 instead ;-)
