We’ve made change recently (last week) on .NET 2.0 you’ll need to use
a different namespace and assembly:
import clr
clr.AddReference(‘Microsoft.Scripting’)
from Microsoft.Scripting.Utils import Func
Func[object, object](targetCallableHere)
Will this work cross-version? (i.e. will it also work on .NET 3 & 4?)

To use Func you just need to do:
import clr
clr.AddReference(‘System.Core’)
from System import Func
Func[object, object](targetCallableHere)
This is equivalent to CallTarget1. You can add more “object, “ or
you can replace object with some other type.
It is of course dependent on .NET 3.

How would someone replace CallTargetX with Func<...> within a script?
For example, how would you change the Invoke calls in onChanged and
onRenamed here:
http://www.ironpython.info/index.php/Invoking_onto_the_GUI_%28Control%29_Thread
I've never seen how to use Func within an IP script, just within C#.

Sounds like it could be a common 'gotcha' especially for newbies
running old example code.
Cheers,
