No. This can also happen for multi-line plain scalars in a non-indented 
flow collection:

 ---
 {
 ?
 multi-line
  key
 :
 multi-line
  value
 }
 ---
 [
 multi-line
  entry
 ]
 ...

So the restriction is more universal. It applies to the first line of 
any non-indented plain scalar. Whether it makes it more or less of a 
quirk is debatable :-)

Yes. I still think >>> and ||| are pretty neat too, but Brian was right 
- at this point, changing --- and ... to anything else would be 
breaking too much backward compatibility. We'll live with them. And 
they do look nice :-)

Have fun,
