I have a couple of questions: 1) I downloaded the stand-alone version and tried "Your first date with JetBrains MPS" but for some reason I can't get the extract method/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's own "routine") 2) How do you debug generated code? Is there a way for MPS to map generated Java or C back to the original DSL?
