Packle

This chapter in the Oils Reference describes Packle, a binary serialization format for object graphs.

It's a secure subset of Python's pickle format.

Advantages:

• Strings are length-prefixed, so they don't need to be escaped and unescaped.
• Exact float representation, with NaN, Inf, and -Inf values.
• Represent graphs, not just trees. (Think "JSON key sharing")
• Strict Byte strings and strict Unicode, not the mess of JSON strings.
