    does anyone have any general objections to adding pytoolz to our 3rd party deps?

    We are both a library and a tool, and as a library we have to be concerned about downstream consumers

    When I say "be concerned" about downstream consumers, what I mean is that every dep we add is another dep we can cause conflicts with for consumers, and then further with its transitive dependencies
