Dan Ingalls wrote the paper on multiple polymorphism in OOPSLA'86,
not Dave Ungar.

Multiple polymorphism (or double dispatching, as I like to call it) works
just fine.  Kurt Hebel reimplemented all of arithmetic in Smalltalk-80
use double dispatching.  He also build a browser that makes it a lot
easier to use and releaves the burden of all the little methods.  We
have nearly finished a paper describing it.
