Hi,  
I have some issue with hosting IronRuby in C# application.

I’ve created Ruby ScriptEngine, created ScriptScope with delegate in it:

> C#  
> scope.SetVariable(“func”, new Action(MyMethod));

but can’t execute “func” from script

> Ruby  
> func(“argument”)  
> fails with ArgumentException “wrong number of arguments (1 for 0)”

but can run it by calling “invoke”:

> Ruby  
> func.invoke(“argument”)

is it possible to execute Delegate like normal ruby function?
