Recipe starting from emacs -Q:

M-: (funcall #'or) RET

Expected result:

An error, as `or' is not a function.

Actual result:

nil
------
Effectively, this makes `funcall' behave as though it were a macro,
even though it is a function.

Probably not a serious issue, but it can confuse people into thinking
that "funcall" accepts macros in general, which it doesn't do. It
certainly confused me (the byte compiler also mis-compiles (apply #'or
nil), which did not help).
