My goal is
to work with low level binary data in Python with convenient tools. Not
necessary high level tools - just convenient for messing with chunks.

Exception handling: There are as many ways to handle exceptions as
there are compilers, all of them with subtle rules around lifetimes of
all the objects that are being excepted over.
I would be interested to see this on binary level, but I doubt such
papers exist. Making a library that can produce diagrams for such
structures will be a good starting point to grok at more serious
performance problem when you switch CPUs.
I think you might enjoy reading about LLVM and their approach to
representing bit-level stuff, and interfacing with various languages'
definitions of exceptions etc:
http://llvm.org/docs/index.html
particularly
http://llvm.org/docs/LangRef.html
from the introduction of the latter:
The LLVM code representation is designed to be used in three
different forms: as an in-memory compiler IR, as an on-disk
bitcode representation (suitable for fast loading by a
Just-In-Time compiler), and as a human readable assembly
language representation. This allows LLVM to provide a
powerful intermediate representation for efficient compiler
transformations and analysis, while providing a natural
means to debug and visualize the transformations. The three
different forms of LLVM are all equivalent. This document
describes the human readable representation and notation.

I think you may have some interesting ideas. I am also interested
in a high level language with ability to get down to the metal, so I
am trying to design one. The trouble is, scouting around for ideas,
you may wind up doing more reading than actually working. Ltu is
particularly dangerous ;-)

I think you should try to design the language you want, according
to your ideas. IME there is no better way to gain respect and appreciation
for other people's work in language design ;-)
When you want to write your compiler, python is there. Or you may find
racket's ability to define alternate syntax languages interesting:
http://docs.racket-lang.org/guide/languages.html
Their home pages is

Have fun ;-)
