Yeah, Significant whitespace is why I won't code in Python anymore. Also, the linked article's comparison of Haskell and Python on readability is an awfully poor comparison, Haskell has notoriously terse syntax, In comparison to Python, which is nearly designed with the sole purpose of having good looking syntax.

but that was the very point of comparing Python and Haskell.

FWIW the Haskell crowd were super-defensive and claimed that Haskell is super-readable (by them).

Now in that article I talk about 'curly bracket' languages in general, meaning those that use symbols (words) to denote blocks rather than indent. And I don't like reading them because of that.
