No, zero is a valid number of identifiers for `define`, which is how
(define (foo) ...)
works. Although it's not very useful to write
(define-values () ...)
it's not a syntax error either, though it would be a semantic error unless
the body returns zero values.

Yes, the parens are definitely missing. Fixed.
