lexical-let*
lexical-let* is a Lisp macro in `cl.el
'.
(lexical-let* BINDINGS BODY)
Like `let*', but lexically scoped.
The main visible difference is that lambdas inside BODY, and in
successive bindings within BINDINGS, will create lexical closures
as in Common Lisp. This is similar to the behavior of `let*' in
Common Lisp.
