      @yukihiro_matz Is the magic comment on by default or off by default? Will existing gems get opted into frozen strings?

      @yukihiro_matz So you need the magic comment in Ruby 3.0 to get frozen strings?

      @wycats No, you just need magic comment for mutable string literals after Ruby3.0.

      @yukihiro_matz This could become like Python 3. It can break gems that mutate strings (gsub! even) and will be hard to track down.

      @wycats I understand your concern. old programs will run by adding one line of magic comment though.

      @yukihiro_matz most programs have dozens or hundreds of third party dependencies.

      @yukihiro_matz and a gem returning an immutable string may be fine in isolation, but when passed to another gem, 💥

          @yukihiro_matz in other words, gems don't say "I take a mutable string", they say "I take a string", so the problems will be subtle.

          @wycats @yukihiro_matz This shows that it’s not that a hard work to upgrade existing libraries.

          @a_matsuda @yukihiro_matz it's not always trivial to understand interactions between many libs.

          @wycats @yukihiro_matz what if his was a VM level setting instead of code level. Default to frozen, VM arg makes them mutable.
