As a file grows, the ability to notice you are in a= frozen string file goes down. It would have been great if Ruby had started= immutable strings by default but that ship has sailed, I think having some= files be immutable will be confusing. I think it is not a big problem because we don't need to aware the directive is exist or not if we use "..." to strings not modified and "...".dup to strings to be modified. --=20 Tanaka Akira
