Internally, Python is a lot like that, too - like in Haskell, the lexer adds in brace tokens when the code is indented an unindented, which keeps the grammar simpler. I guess the main difference here is that Haskell exposes the underlying whitespace-insensitive notation to the programmer, too, whereas Python keeps it hidden.
