Subject: funcallable-p?
Date: Sat, 25 Aug 2007 17:40:51 -0700 [thread overview]
Message-ID: <DHEEKFAFJEFOJHLCFPFDEEIKCAAA.drew.adams@oracle.com> (raw)
What's a good way to test the first argument to `funcall' or `apply', to
ensure that it is appropriate?
`functionp' won't do it, because it allows special forms and macros. I can
imagine doing a case analyis on the function-cell value, but what's a
concise and elegant idiom for this test? I don't see one used in the Lisp
source files; I guess each occurrence there more or less knows what argument
to expect.
