To a beginner who is used to ordinary imperative languages, that Ruby line is extremely difficult to understand. Is `.filter` a method or a property of `xs`? Is `{ |x| x.odd? }` an argument to a method or just a statement that comes after `xs.filter`? If it is passed to `.filter`, why does it not have parentheses around it but the `", "` passed to `join` does?
This all makes sense to a person who knows the language a lot, but wrinkles the brain of a newcomer. Too many concepts to juggle in order to understand. On the other hand, the Python one reads quite easily, even if you may have to go right to left.
The Ruby syntax doesn't seem that different to many other languages. For example:
Python seems to be the odd one out. Imo, its list comprehensions are confusing as hell to "newcomers". For example, when a list comprehension has multiple `for`s, what order are they nested in?
