If I understand correctly, you can still curry with named parameters. You just have to add a little more intelligence. Basically, currying means that the function call was incomplete - we need more parameters before we are satisfied. It's easy to do that with positional - did I get enough stuff. But, using something like Params::Validate, you could build currying for named parameters.

Of course, the trick is making sure you have a good API for the developer to specify currying. I suspect the best way is to just define the API, then have the function automatically curry whenever a required argument is missing.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
