I doubt that.

I used to limit myself to indentation to see which code belonged
to which control. But then I found myself witch controls that
were so nested it was hard to see to which if a particular
else suite belonged and I started to use end markers in comments
to make the structure more visible.

Yes it does, but so does a language that enforces endmarkers.

IME the use of end markers helps too.
