Okay so I was kind of surprised this compiled:
if (null == default(T)) _array[_head] = default(T);

Where T is a generic type parameter

class GenericArray<T> where T : class
{
    public void Insert(T parameter)
    {
        if(default(T) == null)
        {
            Console.WriteLine("null");
        }
    }
}

class GenericArray<T> where T : struct
{
    public void Insert(T parameter)
    {
        if(default(T) == null) // <--- Error here.
        {
            Console.WriteLine("null");
        }
    }
}

It's too bad I don't know if that operation boxes or not.

Or maybe it works in comparisons but not assignments.

public void MyVoid<T>(T something)
{
    if (typeof(T).IsValueType)
    {
        // Not null, so no boxing
    }
    else
    {
        // Nullable, so no boxing
    }
