Data to add

[jplatte]

It can be a somewhat time-intensive task to collect all the relevant data about a feature in addition to just keeping on top of what things are getting stabilized. This is my todo list of stuff that's been stabilized and I've been meaning to add. Help in gathering data and putting it into the right format (simple example, complex example) would be much appreciated.

ToDo (stable):

• Tracking Issue for Stdin::lines forwarder method rust-lang/rust#87096

ToDo (unstable):
_{Needs another update once stabilized}

Had forgotten this existed. There's some things that have been addressed. Don't mind helping with this list if you're happy to give perms for editing issues.

Updated a few things earlier but I'd be happy to let you update any other parts that you know to be outdated :)
