I've always liked this approach to bracketing, since encountering
it in the 1970s as the "off-side rule" (meaning that when indenting
jumped back to the left ("off-side"), the intervening levels of
structure were "closed").
I've often wondered why it wasn't more common, since it makes the
code "mean" exactly the way it looks.
I once "inherited" the maintenance of a text formatting tool written
in Cobol (!), so I had to learn Cobol on the fly. I was astonished
to learn that in this "easy" language, the presence or absence of
a single period in the middle of a nest of IF statements would
completely alter the IF nesting without causing any syntax errors!
What a violation of the "least surprise" principle, when a flyspeck
can make one program read like another!
