The module comment of (guix gexp) says this:
--8<---------------cut here---------------start------------->8---
;;; This module implements "G-expressions", or "gexps". Gexps are like
;;; S-expressions (sexps), with two differences:
;;;
;;; 1. References (un-quotations) to derivations or packages in a gexp are
;;; replaced by the corresponding output file name; in addition, the
;;; 'ungexp-native' unquote-like form allows code to explicitly refer to
;;; the native code of a given package, in case of cross-compilation;
;;;
;;; 2. Gexps embed information about the derivations they refer to.
;;;
;;; Gexps make it easy to write to files Scheme code that refers to store
;;; items, or to write Scheme code to build derivations.
--8<---------------cut here---------------end--------------->8---
