Yes - see https://www.gnu.org/software/kawa/Application-and-Arguments-Lists.html

The basic idea is you can create "arglist" or an "argvector" which is a kind of list
or vector, except the keywords are "marked".  You can then pass this arglist
or argvector to apply.

You can also use "slice" syntax, which is more flexible:

    (fun @arglist) === (apply fun arglist)

You can combine arglists:

    (define xargs (arglist 1 2 key: 3))
    (apply fun (arglist 9 8 @xargs))

> In Racket, which shares the Kawa semantics, there is a special `keyword-apply`: "Like apply, but kw-lst and kw-val-lst supply by-keyword arguments in addition to the by-position arguments of the vs and lst". So it takes a list of keyword objects and internally converts them somehow to the native calling convention.

Regular apply suffixes.
