I LOVE python, it is the weapon I first take to any battle and the language I recommend to beginners. But, I have to admit that the fact that it is so easy to lose track of which "if" a nested "else" belongs to when modifying code, and, I've seen this being the source of so many bugs, that it has changed my opinion about whitespace-significant languages.

Also, I've come to appreciate when I write in say Rust, the fact that I can let go of the syntax, just write and focus on my ideas and let my editor sort the mess at the end.

Having types and removing statements from the language make this much less of an issue

Elm has a whitespace significant syntax, but it too has an excellent code formatter tool.

How does Rust make it any easier?

All clauses are defined within curly brackets like C so indentation has no meaning and you can let tools take care of that.

Also, with editors like vim, you can press % to go to the matching brace (curly bracket). In fact that works in vi too, right from the early vi days; also, in vim, if you position the cursor on an opening or closing brace, it momentarily highlights the other one (at least if that brace is visible on the screen, can't remember offhand if this works even if not visible).

I still like languages like Python and F# though.

But is it any easier to tell which clause an else is connected to? Python has tools too.

When you refactor, yes. In python, say you add a new condition inside a condition, it's really easy to get lost and indent the wrong one to the wrong level.
