The one-function protocols strike me as unidiomatic; why not use functions directly? `(fn […] …)` would work just as well as `(reify P (f [this …] …))` (`this`

The one-function protocols strike me as unidiomatic; why not use functions directly? `(fn […] …)` would work just as well as `(reify P (f [this …] …))` (`this` is never used). Update: I looked at the code again and noticed that `stdin-transport` implements two protocols. Guess I need to think a little bit more about this.
