No... this isn't Python. :)

There are only two possible solutions that I am aware of:
  1. Add text to this message, e.g., "There may be a 
     missing 'end' at an earlier point in the code."
  2. This one is not going to happen: Have more than one
     kind of 'end' -- say explicitly "end def", "end class",
     "end if", etc.
