Issue #18241 has been updated by hernanat (Anthony Hernandez). edit: to be clear, I'm making a distinction between "new string" in the contents-sense, and "new string" in the memory location sense. For example, the `<<` operation on `Array` inserts an array entry and returns `self`, which is why I was initially confused when I saw that the result of `String#<<` was a new string. ---------------------------------------- Misc #18241: Question on String Concatentation Documentation https://bugs.ruby-lang.org/issues/18241#change-94017 * Author: hernanat (Anthony Hernandez) * Status: Open * Priority: Normal ---------------------------------------- Hello, I noticed that the documentation for `<<` and `concat` both state that the result of each operation is a new string. However, while doing some experimenting myself I noticed that this doesn't seem to be the case. The result has the same object id and memory address as the initial string. I also noticed that the underlying C code fore both of these does seem to return the original string pointer at the end. Is this a documentation issue, or is there something else going on that I'm missing? If the former, I'm happy to put up a PR to fix. If it's the latter, I'd appreciate any explanation.
