In the 90's Java/C/C++ land, one needed to implement lists and dicts and such by hand. Then came dynamic Perl/Python/Ruby where all these handy data types like list comprehensions, map, foreach were part of the language. I guess we mistook easy operations on a rich set of default data types as a property of dynamic languages? Now we have Scala, Haskell, OCaml, Rust that have all these handy tools by default, but also strong typing, and type inference on top of that. (Well OCaml and Haskell we had already some time ago, but they were not popular then.)
