flow representation and current support

Can any yaml document be represented fully in flow style?
(with { }  for hashes and [ ] for arrays at all levels)
I assume so, since JSON is a subset.

I ask because a blind programmer on another list mentioned that
braces and brackets are better than indentation when used with
a screen reader.

It should be possible to load one style and dump another,
but I was only able to emit flow style using a JSON Perl module.
What modules and tools should I recommend here?
(The original query was on a Perl list but tools in other languages
could be useful for this purpose).

Is there a longer indenting/flow equivalence example online?
