This new diff fix a issue with boo, the problem is related to methods with
zero parameters but parameters are passed when calling SelectMethod in
Binder.cs

Hi;

Currently reflection does not support methods that have ParamArray attribute
to be called with InvokeMember, like:

... some class 
public static void TestMethod(params string[] param1)
    {
        Console.WriteLine("Test Method 3, one params");
    }
.... some class

Type type = typeof(ParamArrayTest);
        object obj = type.InvokeMember("TestMethod", InvokeBindingFlags,
null, null, new object[] {"param1"}); 

it fails with:

Unhandled Exception: System.MissingMethodException: The best match for
method TestMethod has some invalid parameter.
  at System.MonoType.InvokeMember (System.String name, BindingFlags
invokeAttr, System.Reflection.Binder binder, System.Object target,
System.Object[] args, System.Reflection.ParameterModifier[] modifiers,
System.Globalization.CultureInfo culture, System.String[] namedParameters)
[0x00000] 
  at System.Type.InvokeMember (System.String name, BindingFlags invokeAttr,
System.Reflection.Binder binder, System.Object target, System.Object[] args)
[0x00000] 
  at ParamArrayTest.Main (System.String[] args) [0x00000] 

This patch for Binder.cs and MonoType.cs allows this type of calling, which
by the way does work on MS .NET

I hope that this patch is good enough to go into Mono

Thanks
