Lambda the Ultimate

PeachPy is a Python framework for writing high-performance assembly kernels.

PeachPy aims to simplify writing optimized assembly kernels while preserving all optimization opportunities of traditional assembly.

You can use the same code to generate assembly for Windows, Unix, and Golang assembly. The library handles the various ABIs automatically. I haven't seen this cool project before.

Among the cool features is the ability to invoke the generated assembly as regular Python functions. Nice.

Guido van Rossum reminisces a bit about early discussions of generators in the Python community (read the other messages in the thread as well). I think we talked about the articles he mentions way back when. Earlier still, and beyond the discussion by Guido here, was Icon, a clever little language that I have a soft spot for. i don't think we ever fully assessed its influence on Python and other languages.

With Python 3.5 released, the thing that drew my attention is the support for asynchronous programming through PEP 0492 -- Coroutines with async and await syntax, which added awaitable objects, coroutine functions, asynchronous iteration, and asynchronous context managers. I found the mailing list discussions (look both above and below) particularly helpful in understanding what exactly is going on.
