I believe you can do this
class Foo
{
var bar:Function;
}
//somewhere outside the class
function myfunction():void {trace('hi')};
var foo:Foo = new Foo;
foo.bar = myfunction;
if you have
class Foo
{
function bar():void {}
}
then you must override.
But you have more flexibility if Foo is defined as a Dynamic Class..
