I did not mean multimethods ("generic functions" is a confusing term, since it
also means functions that work for parameters of any time; also "generic"
suggests "generics", i.e. type parameters).
ES4 had a proposal for multimethods but I doubt it will make a come-back.
Adding another dispatch mechanism to JS is a very hard sell. For dyadic
operators, double dispatch is enough.
