Daniel Sockwell wrote two advent blog posts (1, 2) about the problem of dependencies. This resulted in the release of the _ module (aka “lowbar” module), a growing collection of micro packages of less than 70 lines of code. This caused quite some discussion on Hacker News and made it to the top posts list! Good to see the Raku Programming Language in the news!
