no, this code still works with my patch.  the opening brace must be at
the same level as the preceding statement.  this is not a problem,
since the insides of a literal dict can't be a valid Python expression
and vice versa, so you'll get a syntax error even if the misplaced
opening brace is mistakenly taken as the beginning of a dict by the
Python parser.

my current patch does have a problem as stated in my original message,
but this is really just a proof-of-concept.  a patch with no backwards
compatibility problems can be prepared if there is interest.
