Makes me think less of antirez that he doesn’t acknowledge that this is the same design as Microsoft’s BSTRs, which predate sds by many many years.

I also thought of BSTR but in all fairness this idea of prefixing metadata for string types aren't so unique: eg Delphi's string types use a similar scheme: https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Inte...

One obvious advantage of such scheme of course is that you can pass them as-is to C APIs
