Subject: semantics of `eval-and-compile'
Date: Wed, 16 Jul 2008 11:32:07 -0400 [thread overview]
Message-ID: <20080716153214.2F2C19825A@pluto.mumble.net> (raw)
The documentation string in Emacs 22.1 reads as follows:
Like `progn', but evaluates the body at compile time and at load time.
The following program, if put into a file and then compiled and
loaded, suggests otherwise, however:
(defun foo ()
(eval-and-compile (message "at compile- or load-time"))
(message "at run-time"))
When compiled, this file reports `at compile- or load-time'. When
loaded, this file reports nothing. When `foo' is called, it reports
`at compile- or load-time' and `at run-time'. Thus the body is *not*
actually evaluated at load-time; rather, it is evaluated at
compile-time and at run-time.
What is the intended semantics? -- what is documented, what is
implemented, or something else altogether?
