Ironruby core - Nov 2012 - IronRuby hosting - executing C# method

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<object>(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?

No, even in pure ruby code you must use .call to execute a function stored 
in a variable

eg:

f = lambda{ |x| puts x }
f.call(5) # cannot simply use f(5)

This is a side effect of ruby''s syntax which allows you to call methods
without brackets surrounding the arguments
