> significant-whitespace is the worst idea ever

Hear hear! I never heard a single argument for significant invisible characters that makes sense, ever.

Who would want to have a program that fails because you used invisible character X instead of invisible character Y?

A distinction between invisible character X and invisible character Y is a terrible idea. But indentation is very much visible; it's generally more significant to the reader than braces are, so it should be that significant to the computer too.
