Follow-up Comment #2, bug #30611 (project guile):

Even if one were to make the argument that 1.8.7's behavior of having a key
be read as an optional argument was valid, silently dropping the "3" in the
(func 1 #:c 3) in the previous example is problematic.

Consider the following behavior.

$ (define* (funk #:key a) #t)
$ (funk 1 2 3)
=> #t

$ (define* (funk) #t)
$ (funk 1 2 3)
=> ABORT: wrong number of args

IMHO, the first of these two examples should also trigger a
wrong-number-of-args error.
