Using statements are not added automatically for implicit types in lambdas

[donluispanis]

Given the following class

using System.Collections.Generic;

public class MyClass
{
    public delegate void MyDelegate(IDictionary<object, object> dictionary);

    public MyClass(MyDelegate myDelegate) {  }
}

this statement will fail to compile

MyClass myClass = new MyClass((dictionary) => { });

unless we add using System.Collections.Generic; to the file where we new MyClass up with a lambda.

DSharp does not include by default the usings for implicit types (IDictionary in this case) and hence, it's not able to find them. It outputs the following error: error DS0003: Object reference not set to an instance of an object.
