Amen. And, as the (nominal) author of the PEP, the PEP didn't mean to state
an opinion on whether braces are mandatory. It only meant to state how they
should be placed when they are there. It's true that there are other
readings possible, but that's what I meant. If someone wants to change the
wording to clarify this, go right ahead.
