It's OK if this PR is left to sit, or is rejected, but I'm posting it to tie up the last [loose end](Raku/doc#4435.)) I'm aware of regarding `<|w>`. [A search of roast for `|w` reveals one match, just one, no more, no less](https://github.com/search?q=repo%3ARaku%2Froast+%22%3C%7Cw%22&type=code). That demonstrates that although `|w` was "spec"d (speculated) in the design docs as one of a range of `<|X>` features (where `X` is a character class), and is implemented in Rakudo, it is not (currently) roasted, and as the [discussion about this in the doc repo](Raku/doc#4435), led to its removal from the Raku doc, I decided to write this PR.
