[IronPython] DLR and VS-Interactive

Not really an answer, but more of a related topic: have you tried out the Silverlight 1.1 alpha (not the go-live beta), and then the DLRConsole sample?
One dynamic aspect seen there which you don't mention is dynamism in the language-of-the-moment:  you can switch from Python to JScript mid-session and still operate in the same context.

This is more a DLR than an IronPython question.

There are two 'dynamic' aspects that are covered by the DLR extension to the
CLR. One is runtime support for efficient dynamic typing. The other is the
hosting side: console interface, integration with Visual Studio, etc. These
are useful for other (non-dynamic) languages as well. Case in point: F# has
an interactive console in Visual Studio, but is compiled and statically
typed. This second aspect looks more like an extension of the Visual Studio
SDK, if it wasn't taken straight from the VS Integration samples from the VS

In other words: my impression is that the current DLR is made up of two
separable parts:
1. The actual DLR, which enables efficient dynamic typing on the CLR.
2. "VS-Interactive", a set of extensions to the Visual Studio SDK that turn
Visual Studio into an interactive development environment.

Is this where the refactoring is headed?
