informative and funny presentation at pycon 2016 about bytecode manipulation in python.
it's 40 minutes long but useful and informative.

Answer 1

In the presentation:
* Debugger injection is a very good point; I definitely needed this once.
* They mention not being able to execute a code object directly. That's because some of the preamble code is missing; I address this with marshal in method 6 (line 141) here:

Here's a little more info on bytecodes (as well as built-in opcode info) for a few custom commands built using eval() and exec():

Finally... What Does It Take To Be An Expert At Python?

* How "class" and "generator" statements are themselves executable statements (unlike c++, which just generates a memory layout).
This lets you (e.g.) intercept construction of your library class...at the remote end...and enforce construction- or instantiation-time (vs runtime) constraints.
* The presenter -- at length -- shows how Python has very *specific* patterns, and how understanding the mental models lets you wrap / annotate / decorate to assemble powerful, seamless, automatic constructs that just work...on any function... without having to rewrite anyone's code.
* He also shows how you can just figure out the syntax as you go, without ever leaving Python.

Thanks, I'll give it a check
