Code example:

This is your actual problem: you have a whole page of code nested four
times. That’s not going to be readable no matter what editor support
you have; you need to refactor it.
This is of course a silly example.
With smaller blocks of code where the whole thing does fit easily on
the screen, you usually don’t get lost—and if you do, most editors
already help you. They can draw a different colored line down the left
side of each block, or have a keystroke to briefly highlight the start
of the current block (I use that in emacs whenever I’m forced to edit
code that someone insisted on writing with 2 or even 1 space per
indent—or, worse, inconsistent indents), or collapse the current block
to an outline (which would actually be less useful if the outline had
to show 3 lines instead of 2).
Sure, none of that is sufficient with huge blocks of code, but I don’t
see how an “end if” would help. Who cares if they’re the same color
when you can’t see them both anyway (which, by definition, you can’t
when there’s a page or more of code between them)? All the “end if”
really tells you is that some block whose start you can’t see ends
here, which you can already tell from the dedent. (And, unlike C,
where you need a closing brace because the dedent could be a lie, in
Python it syntactically means the very thing you hope it means.)
I've been doing software engineer for a few decades... I like to think I
know a little bit about it :-) ... believe me I have more than one use
case where this would be very useful for me.
cheers,
Jan
