A channel, a sewer, Alabama, and a sunset walk into a bar:
- A Lua implementation of Go-style coroutines and channels, inspired by a channel implementation by Russ Cox, who is a major contributor to Plan 9 and Go
- The infrastructure underneath New York City, sewers, subways, the whole shebang
- “Alabama” by John Coltrane, a jazz cadenza
- Sunsets, as always
