[ruby-core:71472] [Ruby trunk - Feature #11473] Immutable String literal in Ruby 3

Issue #11473 has been updated by Mike Pastore.


Has anyone suggested introducing new quote-like operators to define mutable strings in Ruby 2.3 (with immutable string pragma) and 3.0? I was thinking something like:

~~~
# immutable without interpolation
'foo'
%q{foo}

# immutable with interpolation
"bar"
%Q{bar}

# mutable without interpolation
String.new('foo') 
%y{foo} # proposed

# mutable with interpolation
String.new("bar") 
%Y{bar} # proposed
~~~

Also, what about mutable vs. immutable heredoc?

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

This ticket is place holder to discuss about that.
