Hello,
C-h f apply says:
| ...
| With a single argument, call the argument's first element using the
| other elements as args.
Issue 1: This doc sentence has to be moved after the following example,
because that example:
| Thus, (apply '+ 1 2 '(3 4)) returns 10.
is an example for the more widespread syntax.
That sentence actually explains a special case: it tells that this is
also allowed:
(apply '(+ 1 2)) ==> 3
Issue 2: The byte compiler currently miscompiles such expressions:
Expected:
(funcall (lambda () (apply '(+ 1 2)))) ==> 3
but
(funcall (byte-compile '(lambda () (apply '(+ 1 2)))))
~~> Error: Invalid function: (+ 1 2)
AFAIU this is `byte-optimize-apply's fault:
(byte-optimize-apply '(apply '(+ 1 2)))
==> (funcall '(+ 1 2) '+ '1 '2) ; Ouch!
TIA,
Michael.
