checkback

Have you ever had to include a reference in your code so you can check back on it later, but then you forget?

// can't do this until generic associated types lands:
// https://github.com/rust-lang/rust/issues/44265

checkback is a tool that scans your source code for links to GitHub issues and StackOverflow questions, queries them using their APIs, and reports if any have had any updates within the last month. With luck, someone will have posted an answer, fix, or workaround for your problem, meaning you can update your code and remove the link.
