> It also doesn't take 'many years' to internalise for/while loops, these are fairly basic constructs which are learned by most novices in the beginning of an introductory programming course.
The comment is referring to the patterns becoming ingrained in the mind through years of use, not that learning how to produce a while loop for the first time takes years.
There's not much to be ingrained after you learn how for/while loops work, and there's not much in the way of learning how map/filter, or overloaded functions work. I wouldn't even consider the overloaded '+' operator as a loop, you can think of it as a single operation, it's an implementation detail.
