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

Subject:        [Ironruby-core] IronRuby hosting - executing C# method
Sent by:        ironruby-core-boun...@rubyforge.org



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?
