[ruby-core:117524] [Ruby master Feature#20350] Return chilled string from Symbol#to_s

Issue #20350 has been updated by ko1 (Koichi Sasada). `Symbol#name` returns frozen string. It is not enough? ---------------------------------------- Feature #20350: Return chilled string from Symbol#to_s https://bugs.ruby-lang.org/issues/20350#change-107913 * 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. -- https://bugs.ruby-lang.org/
