[IronPython] DLR question

Let's break it down:

1. Will IronRuby will run real ruby programs? Yes
2. Is Rails is a real ruby program? Yes

So, those two points say that IronRuby will run Rails. We run "hello world" today. Cool.

3. Will IronRuby and IronPython will be able to interop? Yes, but in a constrained way.

So, you'll be able to use IronRuby code from IronPython, and visa versa. However, this is constrained. As Dino said, you won't be able to subclass. So ...

4. Will IronPython run Rails? No, not pure vanilla Rails.

Rails controller/models depend on subclassing, so you wouldn't be able to do this:

class MyPythonController(ActionController.Base):
  def index():
    render(partial='foo')

... though it does seem awesome! So, someone need to write a layer in between to create an IronPython API for Rails. But I'm not sure any Python developer would want to ever do that. :)
