[IronPython] 2.0B1 Hosting: Creating Python Types

In general you shouldn't need access to CodeContext for doing anything - unless you're writing an API which will be consumed by script code. And the hosting APIs don't expose CodeContext instances so it can be challenging to get one without jumping through hoops.
Obviously there's a bunch of things people want to do that are Python specific and aren't covered by the DLR hosting APIs. It'd be interesting to collect all of those things so that we can make sure we get all of the features that people want.
So far I think the interesting ones would include:
module access (built-ins at least and possibly Python modules)
type caller (which will actually going away, so no big deal there, but might be worth a discussion)
There's also some cleanup here for example creating ScriptScope's from the DLR doesn't give you a very usable Python module but we'll be fixing that.
Are there other things that jump out at people as missing? Also, is there much interest in a 1.1 compatible hosting API or should we just expose this additional functionality?

Does this mean that we shouldn't be creating CodeContexts? I'm using
the class "IronPython.Runtime.Operations.PythonTypeOps+TypeCaller" to
construct new objects from Python types. This process requires a
CodeContext, which I'm currently building from scratch as needed.
(The same approach could be used with the PythonType
"IronPython.Runtime.Builtin.file" in order to build a Python file
object a little more efficiently.)
