Can you use LINQ types and extension methods in IronPython?

IronPython 2.7 finally bridges this gap with the clr.ImportExtensions method which adds the extension methods from a namespace to the target types e.g.

>& 'C:\Program Files\IronPython 2.7\ipy.exe'
IronPython 2.7 (2.7.0.40) on .NET 4.0.30319.225

>>> import clr
>>> clr.AddReference("System.Core")
>>> from System.Collections.Generic import List

which brings it into line with IronRuby 1.1’s using_clr_extensions method.
