These code pieces are not equivalent -- you have four lines of code in 
the first piece, only three lines in the python piece; in other words, 
if the "end;" were not on screen, you would still have no idea if it was 
the whole block or not; in still other words, the "end;", just like the 
dedented line, provides the context.
