91 ## (in this case JSON)

96 # unpack the JSON string into a class

104 This role is designed for those times when you need to
105 serialize into many different formats or I/O options.
107 It basically allows you to choose the format and IO
108 options only when you actually use them (see the
109 SYNOPSIS for more info)
111 =head1 SUPPORTED FORMATS
133 B<NOTE:> The B<StorableFile> I/O option is not supported,
134 this is because it does not mix well with options who also
135 have a C<thaw> and C<freeze> methods like this. It is possible
136 to probably work around this issue, but I don't currently
137 have the need for it. If you need this supported, talk to me
138 and I will see what I can do.
