I'd be more understanding if Vim didn't explicitly > outline the escape sequences it does allow inside a collection. Here are the reasons: 1. People assume that `\[' is `[', not `\\[', there are already lots of scripts that do need fixing and treating `\[' as `\\[' is non-obvious. 2. Other most popular regex engines treat `[\[]' as `\[', not as `(\\|\[)'. 3. Parenthesis matching has `\['-`\]' and `['-`]' pairs, not `['-`\]'.
