A function with two arguments. Harder to understand than a Monadic Functions.

writeField(name) is easier to understand than writeField(output-Stream, name)

The meaning of both might appear clear, the first glides past the eye easily presenting its meaning.

The second requires a short pause until you learn to ignore the first parameter (output-Stream) — which results in problems because we should never ignore any part of code. The parts we ignore are where the bugs will hide.
