His advice that follows, to leverage polymorphism to avoid switch statements isn't bad per-se, but his reasoning, that 6 lines is too long, was a reflection of his desire to get every function as short as possible.
In his own words, ( page 34 ):
> [functions] should be small. They should be smaller than that. That is not an assertion I can justify.
He then advocates for functions to be 2-3 lines each.

That's both true, but long way away from "every line should have it's own method", but I guess parent exaggerated for effect and I misunderstood them, I took it literally when I shouldn't.
- eterm 9mo agoI've edited my comment to add more context to that quote. He absolutely advocated for the most minimal of function lengths, beyond what is reasonable.
- zephen 9mo agoHe has expressed admiration for lisp, and he comes from a time before IDEs. These may color his desired level of complexity.
