I was delighted when I recently came across `bound-and-true-p' in
standard Emacs. But what about `fboundp-and-funcall'? Like this:
(defmacro fboundp-and-funcall (function &rest arguments)
`(let ((function ,function))
(and (fboundp function)
(funcall function ,@arguments))))
;; arguments not eval'ed in case of failure
(fboundp-and-funcall #'foo (setq baz 'bar))
nil
(boundp 'baz)
nil
(fboundp-and-funcall #'identity 'foo)
foo
WDYT?

I think "Why?".
The trivial expansion is just as clear (nay, clearer), and nearly as succinct.
(and (fboundp function)
(funcall function ,@arguments))))

Just one opinion.
(Of course, I feel the same about `bound-and-true-p', which has the additional disadvantage that its name doesn't proclaim that it returns the variable's symbol.)
