Issue #20350 has been updated by Eregon (Benoit Daloze). Matz already approved this change above, so I think the only missing thing is a PR to implement it. It might be late to add this in 3.4 though, but it could be merged early in 3.5 dev. ---------------------------------------- Feature #20350: Return chilled string from Symbol#to_s https://bugs.ruby-lang.org/issues/20350#change-110502 * Author: Dan0042 (Daniel DeLorme) * Status: Open ---------------------------------------- During Ruby 2.7 development there was an attempt to return a frozen string from Symbol#to_s (#16150#note-22) This had to be rolled back due to incompatibility, but now we have chilled strings (#20205) Symbol#to_s can safely return a chilled string, giving developers time to fix warnings before switching to a frozen string. ---Files-------------------------------- Screenshot 2024-11-06 at 14.00.47.png (118 KB) -- https://bugs.ruby-lang.org/
