  * Make compileToCore return the module name and type environment along with bindings
  
    compileToCore returned just a list of CoreBind, which isn't enough,
  since to do anything with the resulting Core code, you probably also
  want the type declarations. I left compileToCore as it is, but added a
  function compileToCoreModule that returns a complete Core module (with
  module name, type environment, and bindings). I'm not sure that
  returning the type environment is the best way to represent the type
  declarations for the given module, but I don't want to reinvent the
  External Core wheel for this.
