Either rethrow the original Exception:

catch(Exception e)
  {
   writeln(e.msg);
   throw e;
  }

In this case, if nothing else catches the exception, then it will 
go back to main. If anything else does catch it, it can rethrow.

Or you can do as suggested above throw a new Error:

catch(Exception e)
  {
   writeln(e.msg);
   throw new Error(e.msg);
  }

If nothing is catching Throwable or Error (and nothing should 
be), then the error will go all the way back to main just fine.
