YAML is hard to understand for a blind developer because if he
arrows up or down the text, he hears the current line spoken,
but he doesn't know how many spaces is that line indented. YAML
is useful only visually, but not all the programmers can see,
so from this point of view, other configuration modules are
better.
[..]
It is also possible to hear the number of spaces when using a voice
synthesizer, but it is not very friendly to use a language like
Python. The languages like perl, Java or C# that use blocks
enclosed between { and } are much more friendly.
YAML, the format, supports "flow" style collections which
use {} and [], as JSON does.

I don't think Perl's YAML modules support emitting in this style yet,
although you may be able to hand-write YAML this way.
