The author raised an interesting point with respect to syntax highlighting for types. I find the convention that literals be typed (ints, strings, etc...) to be inappropriate. That is very low-level and these should always be inferred. Where typing should exist is at the level the author suggests, such as * Iterators * List-like structures * Functions that return option types and other more abstract structures.
