I'm running into an issue with escaping numbered placeholders in rush. The docs mention you can escape {} with {{}} which works great, but what about when you need literal text like {35}?

I tried using {{35}} expecting it to output {35}, but it doesn't work - seems like it's still trying to parse it as a numbered placeholder or something. Right now I'm having to do weird stuff like $(printf \{35\}) just to get a literal {35} in my command, which feels cumbersome, i.e. not elegant.

Would it be possible to make the escaping work consistently? Like {{1}} -> {1}, {{2}} -> {2}, etc? It would make sense to follow the same pattern as the empty braces.

Not sure if this is a bug or missing feature, but it would definitely make life easier when working with commands that need literal curly brace notation with numbers in them, as could be the use of extended regular expressions or PCRE2 as either commands like sed, grep or awk.
