I have a couple of questions:<p>1) I downloaded the stand-alone version and tried &quot;Your first date with JetBrains MPS&quot; but for some reason I can&#x27;t get the extract method&#x2F;surround with to work.  Is that a bug or is there some special condition for refactoring to work?  (I try to extract the drop and turn right into it&#x27;s own &quot;routine&quot;)<p>2) How do you debug generated code?  Is there a way for MPS to map generated Java or C back to the original DSL?
