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.

Thanks

Anthony
