C# 4.0: Reflecting Named & Optional Parameters

I wrote few tests to understand Named and Optional Parameters. Now it's time to reflect.
I wrote few tests to see the what happens behind the scene.

Tests.
1. Reflecting Optional with default values

public void MethodWithDefaultValue(string name ="N/A", int cound =50)
 {
 
 }

gets converted to

public void MethodWithDeffaults([Optional, DefaultParameterValue("N/A")] string name, 
[Optional, DefaultParameterValue(50)] int count) 
{
}

You can declare a method using Optional Attribute, which allows you to have optional reference objects.

2. Reflecting Optional parametes when ommitted : When above method is called

public void ReflectMethodSignatureForOptionalWithDefaultValue()
{
ReflectClass optionalWithDefaultValue = new ReflectClass();
optionalWithDefaultValue.MethodWithDefaults();
}

gets converted to

public void ReflectMethodSignatureForOptionalWithDefaultValue()
{
new ReflectClass().MethodWithDefaults("N/A", 50);
}

Default values for the optional arguments are injected in the caller code.

3. Reflecting Named Parameters: if method in Test 1 called with named parameters,

public void ReflectNamedParametersCallerCode()
{
   ReflectClass optionalWithDefaultValue = new ReflectClass();
  optionalWithDefaultValue.MethodWithDefaults(count: 20, name: "Hello");
}

gets converted to

public void ReflectNamedParametersCallerCode() 
{ 
 ReflectClass optionalWithDefaultValue = new ReflectClass();
 int CS$0$0000 = 20;
string CS$0$0001 = "Hello";
optionalWithDefaultValue.MethodWithDefaults(CS$0$0001, CS$0$0000);
}

In the caller code,  A  local variable is created for every named parameter.
