Mark,
If you like to quote them, there's no problem with that. If you use whitespace in
your keys,
you'll want to quote them. I don't quote them for the same reason that I usually skip
optional
parentheses: I like cutting down on all of the punctuation.

Someone asked me how to count to 10 in Perl:
push@A,$_ for reverse q.e...q.n.;for(@A){$_=unpack(q|c|,$_);@a=split//;
shift@a;shift@a if $a[$[]eq$[;$_=join q||,@a};print $_,$/for reverse @A
