it's a pickler that can be made safe, explicit and works with your classes

explicity register serializers for classes, or you use to_pack and from_pack handlers on your class

uses msgpack as the base serializaton layer. very configurable. can pack/unpack lambdas (this isnt safe, but its fun)

@earonesty That looks interesting!

Guess I have to check within borgbackup whether we would like to use your code instead of some homegrown stuff.
