First, I think using + for vector-append is a bad idea.
It's questionable for strings, but if + on vectors would be
better to mean vector addition - i.e. mapping + element-by-element.
(Of course my exposure to APL is influencing me here.)
Second, Kawa has some half-assed support for "multi-methods":

That could be enhanced.
