Definitely. GHC and Hugs implement it, don't know about the others.
But note that you do not necessarily need it. Often a simple first-class
function, or a record thereof, is enough (in fact, "dynamic binding" is
just the OOO way of saying "calling a first-class function"). In typical
functional programming style, you need the general thing only rarely.
