Polymorphism and Collections

Thank you dlorde!

I feel a little ashamed because the same topic was on the first page of the forum, with basically the same title: http://www.codeguru.com/forum/showthread.php?t=479574

What should I say about Visitor.. it's a very powerful pattern... freakin genius actually!!
And it's easier to learn than it might seem.

That's right, and that's something for Mr. dlorde to contemplate.

I'm saying this because dlorde strongly has argued that the Visitor pattern should be avoided because it's likely to not being understood by maintainers of your code. That's nonsense. The Visitor pattern is in the public domain and should be understood by every Java programmer - unless they're a moron of course or being recruited from some burger flipping shop to save the money an educated programmer would cost.
