I don't think currying can reasonably be combined with optional parameters. At least I've never seen a useful way to do so.

In a previous article (http://fr.umio.us/why-ramda/) I discuss more thoroughly how I would tend to use this currying, namely to build up collections of useful functions, often in points-free style, so that major parts of the application would end up as (ideally well-named) functions, each which serve as pipelines of these smaller functions, passing data through the system.

I do find this significantly more readable, but _de gustibus non est disputandum_.
