Using APPLY with functions with #!key arguments

[Duncan Mak]

I think this used to work in older Kawa releases, but how do I use
APPLY to invoke a function like this in Kawa 3.0?

#|kawa:1|# (define (foo x #!key y) (list x y))

#|kawa:2|# (foo 1 y: 2)
(1 2)

#|kawa:3|# (apply foo (list 1))
(1 #f)

#|kawa:4|# (apply foo (list 1 2))
gnu.mapping.WrongArguments

#|kawa:5|# (apply foo (list 1 y: 2))
gnu.mapping.WrongArguments

In Kawa 2.4, this worked:

***@furigana:~/Downloads/kawa-2.4/bin$ ./kawa
#|kawa:1|# (define (foo x #!key y) (list x y))
#|kawa:2|# (apply foo (list 1 y: 2))
(1 2)
#|kawa:3|# (apply foo (list 1 2))
(1 #f)


Happy holidays!

You can do this:

(apply foo (arglist 1 y: 2))

which is the same as:

(foo @:(arglist 1 y: 2))

This chapter in the manual should be helpful:

Thanks Per! That worked!
