Sometimes it's worse than just ugly.  See the entry in the Perl FAQ:
http://www.perl.com/pub/doc/manual/html/pod/perlfaq4.html#What_s_wrong_with_always_quoting

Not likely that anyone would be using something as a hash key that would
suffer from being stringified, but possible.  It's definitely a bit slower
as well, but that's below the noise level.
