9 years ago It's explicitly forbidden, to avoid confusion/security issues/clashes. / is basically the initial reason for having key names this restricted. Maybe simplekv will become hierarchical in the distant future, but I think that might even run afoul the "simple" part =).
I was wondering what your opinion is on allowing / in keys.
The rationale behind it is that most if not all backends allow it, and some backends like S3 (AWS docs) and file systems handle this in a way that makes the keyspace much more organized.
I would see this purely as a change in some backends, and it's not supposed to affect the API semantics to make it in any way (pseudo-)hierarchical.
If you think this has merit, I would come up with a PR.
