I think this is pretty cool. Instead of thinking it as functions on steroids, I'd prefer looking at it as a powerful callable abstraction.
How does macroexpand-time validation play with apply (the function)? What happens if I do (map some-outfn coll) ? Also implicits confused me a bit. At first I thought they were parameter defaults. But it seems they're some sort of inheriance mechanism for callables. BTW, thanks for taking the time to write a detailed readme. I know this is a young project and it's probably in heavy development. It shows professionalism (yes, professionalism in an open source context is a thing) on your part.
