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#.

Could someone pop an example of this on http://www.ironpython.info?
Sounds like it could be a common 'gotcha' especially for newbies
running old example code.

Cheers,
