P4D = E4X style embedded DSL for Python but without E and X.

The main feature of P4D 1.2 are *Bytelets*. While the primary purpose
of P4D 1.1 was the support textual data which can be considered as
isomorphic to XML the new release is focussed on binary data. Bytelets
are P4D objects that are assembled from hexcode which is reified as a
Hex object. Bytelets can also be serialized as Hex objects which makes
them apt for low level communication. Bytelets can be used to parse
hexcode into other Bytelets of the same structure and Bytelets can be
cloned like object prototypes which makes it easy to produce sequences
of variations of one Bytelet ( usually you do not derive from a
Bytelet but modify a prototype ).
