I find superlong indented blocks in Python a bit awkward, although can't explain why. When I look at a long class definition, for example, it just begs to be closed with end or "}". Small blocks though look definitely better without the block braces.

I'm thinking about introducing an optional end and leaving it to the taste of a programmer. Not sure yet.

    def something:
        alpha()
        omega()
    #end

  def something:
    ...
  end def

I can't say I'm a fan, but at least you'd be making it mean something if you did that.

(Also: why make it optional at that point? Seems like it should be required for simplicity's sake)

It would be nice, however, to have some optional verification mechanism that allowed you to stay minimalist for as long as you wish, and to use closing tags for verification and/or aesthetical reasons - for example, when closing a superlong block.

My point with braces is that you dont have to indent the code then - which is dangerous :)

I have inherited a couple of PHP and C projects that have taken weeks just to indent to be readable - before i can even begin to work on them! (admittedly that is more of a PHP problem). Forced indentation makes definite that everything is obvious: addign curly braces is purely asthetic IMO :D

    (defun indent-buffer ()
      "Indent entire buffer"
      (interactive)
        (indent-region (point-min) (point-max) nil))
