Subject: Anaphoric macros like when-let
Date: Sun, 27 Aug 2017 01:17:13 +0530	[thread overview]
Message-ID: <1a0f67f3.AEAAO93SX5gAAAAAAAAAAAPWCvIAAAACwQwAAAAAAAW9WABZodBb@mailjet.com> (raw)


Is there a Scheme or Guile equivalent to Emacs Lisp's `when-let' ?

Basically, I'm looking for a shorthand to express this:

(let ((x (foo))
  (when x
    (bar x))))

as this:

(when-let (x (foo))
  (bar x))
