Language support
Functional programming languages, such as Erlang, Scheme, ML, Haskell, F#, and Scala, all have first-class functions. When Lisp, one of the earliest functional languages, was designed, not all aspects of first-class functions were then properly understood, resulting in functions being dynamically scoped. The later Scheme and Common Lisp dialects do have lexically scoped first-class functions.
