Subject: [ruby-core:70894] [Ruby trunk - Feature #11473] Immutable String	literal in Ruby 3

Issue #11473 has been updated by Andrew Vit.


Hi Rodrigo, I think you need to look into the implications of what you are proposing here. 

For example: In one place you use the string literal "name" e.g. `@db_columns = ["name"]`. In a different context you perform `"name" << ",email"` for a different purpose. If these become unfrozen instances of the same object, then both would be mutated unintentionally. This is why "unfreeze" does not exist.

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

This ticket is place holder to discuss about that.
