@end example
@end defun
@defun compiled-function-p object
This function returns @code{t} if @var{object} is a function object
implemented in byte-code or machine code.
@end defun
@defun subr-arity subr
This works like @code{func-arity}, but only for built-in functions and
without symbol indirection. It signals an error for non-built-in
