Scheme

Scheme is a popular [[dialect of Lisp]], and has many descendants including [[Racket]].

Misc

In Scheme, a * in a function name means “repeat throughout a list.”

Although [[Emacs Lisp]] is not a Lisp, it has two forms of let: let and let*, where the latter lets you write code like this:

(let* ((foo "foo")
       (bar (concat foo "bar")))
  (message "%s" bar))

In this example, foo is able to be used in the definition of bar, while if this were a let form, this would report an error.
