Dear Maintainer, I've run into a problem with ruby code that depends on anonymous block forwarding. This runs into a bug in ruby 3.1.2, and that means this code doesn't work on debian bookworm. This bug was reported and fixed in upstream ruby at: https://bugs.ruby-lang.org/issues/18673 The fix released in ruby 3.1.3 (November 2022). The fix can also be found at https://github.com/ruby/ruby/pull/5761/files Please can you backport this fix to the debian ruby 3.1 package. Many thanks, Andy
