Original poster is right by all accounts, of course. Now, let's come up with exotic significant indentations.

function xyz(a, b):
|   var x = 2

|   if true:
|   |   do_something()
|   else:
|   |   do_something_else()

|   anyway()

Pro: Your editor no longer needs to implement indentation hints.

Con: Looks obstructive if not highlighted like an indentation hint.

Your turn.
