>For instance, let's look at the whitespace thing.
I immediately fell in love with significant whitespace. Since I was already indenting anyway, why not make it meaningful and skip the additional overhead of matched curly braces?
I am in the same camp. Interestingly I also find Scheme's approach quite nicely: The syntax is so uniform and thus the editor support so good, that you can just pretend that you have significant whitespace and that the parens are just a hint for your editor.
