This will create an unsorted list. You'd have to use
string_list_insert() here for a sorted list, or
unsorted_string_list_has_string() in the earlier call.

It's unfortunate that string_list makes this so easy to get wrong.

This is getting really off-topic (since it sounds like we'd probably
want to use an ordered list here), but is it crazy to think that
basically every use of an ordered string list could just be a hashmap?

Does a hashmap guarantee an order?
I thought we had an example of an ordered list in the submodule code
but could not find it, maybe it is gone already or did not rely on the order
as I thought.

It turns out we make never use of a custom compare function in
the stringlist, which helps gaining confidence this use case is nowhere
to be found in the code.

And then the sometimes-sorted/sometimes-not duality of string-list could
go away?

Sounds good, ship it. :-)
