Hey Shawn,

I'm a little concerned that changing the current behavior to favor name
over position will break backwards compatibility... hold off on switching
the behavior for a 2.0 release?

Maybe we can come up with a notation to say "Even if this is an integer
treat it as a string that names a column instead of a column number" for
fields that can be used in ambiguous situations like this.

Yeah, I was wondering about both those ideas too. Wait until 2.0 and/or add a 
new flag to toggle the behavior change.

I think the main challenge could be how to name such a flag :)

Possibly another idea for 2.0: allow something like ~/.config/datamash/ where 
users can add these kinds of toggles according to their preference. If we're 
going to go ahead with a major refactor for 2.0, I bet there are users who will 
want to be able to selectively force a whole bunch of deprecated behavior, and 
a config file would be best for that.
