I prefer not to be forced to use correct indentation. I do so as a matter of course. And on the odd occasion I have some reason to use odd indentation, I want to be able to do that too. I like to write my code according to my own judgement. I don't feel that indentation ought to be part of a language, just part of the code.

That said, I do sometimes write in Python and I have nothing against the language. This isn't meant to be an attack on Python.

Edit: also, the indentation in the first example is obviously just a means of illustrating that whitespace is non-significant with this project. I don't think they're suggesting code ought to be written without correct indentation.
