Exception when using .? operator for nullable fields

Looks like the following will try to create Nullable for Nullable.

    class Scope
    {
        public int? Value { get; set; }
    }
    
    class Program
    {
        static void Main(string[] args)
        {

            var interpreter = new Interpreter();
            var lambda = interpreter.Parse("Scope?.Value", new Parameter("Scope", typeof(Scope)));
            var result = lambda.Invoke(new Scope());
            Console.WriteLine(result);
        }
    }

this will throw an exception

 System.ArgumentException: GenericArguments[0], 'System.Nullable`1[System.Int32]', on 'System.Nullable`1[T]' violates the constraint of type 'T'.

Oh I didn’t see your pull request. There’s actually an existing method that does the check already: GenerateNullableTypeConversion.
