Scheme is a popular [[dialect of Lisp]], and has many descendants including [[Racket]].
In Scheme, a * in a function name means βrepeat throughout a list.β
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.
