Are you adding # frozen_string_literal: true to your config files

Stéphane Paquet asked in Rails

I was wondering if some of you are adding # frozen_string_literal: true to their config files?

This never became the default in Ruby 3 unfortunately. See:

I don't use it, but I probably should although I'm sure I modify strings like this more often than I realize. It's a pretty great performance improvement when you can use it!

Some more good reading:

I cannot agree more regarding the performance improvement. I also think it's a good practice to avoid changing a string that we wanted to be static ;-)
