I guess that the problem is that the following 
becomes ambiguous:

key:
    - 3

Is this a list with one entry, or a text node 
with value "- 3"?

|     Bananas: Ripe

If we allow this, then we'd need to quote
all multi-line keys; since according to
a recent specification, the first one is
equivalent to...

Fruits: %
    Oranges Apples: @
        : Granny Smith
        : Macintosh
    Bananas: Ripe

Question.  Could your grocery list end up with duplicates?
Does order matter?  If the anwer is "yes" to either of those,
then it is a new information model.  ;(
