title: Removing class from dynamic assembly / module
body: <p>I am working on emitting a class that is based on user's input. Dynamic classes are convenient, since user is free to comeback later and change the input, and program will re-emit new class.</p>
  
  <p>If user comes back later and decides to make some changes, existing class that is already in the assembly/module needs to flushed. How to remove the dynamic class ?</p>
