Not really. The corresponding example with explicit hash would be

{'HashSyntax' => {
                  'EnforcedStyle'   => 'ruby19',
                  'SupportedStyles' => %w(ruby19 hash_rockets)
                },
 'SpaceAroundOperators' => {
   'Enabled' => true }}

and it has the same problem.

The problem seems to be that (let (smie--parent) (smie-indent--parent))
called between "=>" and "{" doesn't stop at "=>", but goes straight to
the parent "{".

Not sure how to fix that best with the current grammar. Stefan?
