Scalars that are used as numbers, then as strings are not converted to
JSON properly. They end up being output without being quoted. E.g.,
my $data = {};
$data->{test_var} = 0;
$data->{test_var} = 'blah';
if $data is encoded, it will output {"test_var":blah}
This will be fixed in version 0.08. If you are in urgent need of the
fix, you can download version 0.07a at
http://perl.regexguy.com/dist/JSON-DWIW-0.07a.tar.gz
This is the only change since version 0.07, but be aware that the fix is
still in the testing phase.
