Subject: [ruby-core:70562] [Ruby trunk - Feature #11473] Immutable String	literal in Ruby 3

Issue #11473 has been updated by Tsuyoshi Sawada.


As for a "finer-grained range than a whole file" directive, it reminds me of the `using` method. Their scope look similar to me. Can we have built-in modules named as `FrozenString` and `UnfrozenString`, which give special interpretations when used with `using`?

    using FrozenString

      # string literals are interpreted as frozen

    using UnfrozenString

     # string literals are not interpreted as frozen

Feature #11473: Immutable String literal in Ruby 3

----------------------------------------
Matz said "All String literals are immutable (frozen) on Ruby 3".

This ticket is place holder to discuss about that.
