Functional Programming Twitter: do we have a term for the function given to a HOF? E.g., if I call `map` on `f`, what would you call `f`? The "provided" function? The function "parameter" (messy around parametric polymorphism)? Something else?

funarg. We've had it since the 70s. It's short, simple, self-descriptive… hard to beat.

Funarg sounds like something a function threw up after panicking on a bad argument, but I guess that's a matter of taste. :-)
