You can't redefine a method on a sealed class at runtime.

Actionscript question Thanks for that info. I'm not really sure about how things work internally, besides some vague references to "traits" the documentation doesn't help too much - can you redefine member methods on a particular instance? What I mean is this: var foo : Foo = new Foo(); foo.bar(); // Does something foo.bar = function() : void { doOtherStuff() }; foo.bar(); // Does something else -J On Tue, Apr 29, 2008 at 10:14 AM, Gordon Smith <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: I think there is additional overhead in calling an anonymous function (i.e., your 'var foo:Function = ' case). And I don't think that the rules for what 'this' is, when the function executes, are the same.

I assume you can call Bar.foo() in both cases, and foo shows up as a variable in describeType() in the second instance? Are there other details I'm not aware of?
