Hi!

Please, see the attached REPL session.

scheme@(guile-user)> ((lambda* (a #:optional (b (+ a 1))) b) 1)
While compiling expression:
ERROR: unbound var a-492
scheme@(guile-user)> (define f (lambda* (a #:optional (b (+ a 1))) b))
scheme@(guile-user)> (f 1)
$2 = 2
scheme@(guile-user)> ((lambda* (a #:key (b (+ a 1))) b) 1)
$3 = 2
