Learning Functional Programming in Go

Long parameter lists will change over time and are inherently difficult to understand

This statement makes a lot of sense. The rest of this chapter will expound on this statement. We'll explore how we can manage an API that could change over time and that might need more than a few parameters to get the information it needs to complete its task(s).

If we compose our application like Beethoven, starting with a general idea of what we want to accomplish and beating our program into shape, then we might not know exactly what parameters an API will need at first.
