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:

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,

Ok cool. I've used Func<> from C# before. That did the trick. Thanks.

Yes. CallTarget’s were really a part of IronPython’s internal
calling convention for used defined functions. We kept CallTarget0
around
because
we knew lots of users had come to depend on that one when they
needed a delegate type. But we removed all the others and switched
to using
Func<…>
internally. Ideally you can switch to using Func<> as well.

Subject: [IronPython] CallTargetX delegates
In IronPython 2.6 beta 2, did the CallTargetX delegates get moved
to another module or were they simply removed altogether? The only
delegate in
IronPython.Compiler is CallTarget0. I checked IronPython 2.0.2 and
it has up
to CallTarget16.
