A change wouldn't need to be drastic, though. I think suggestions from the old thread like "StringAtom" or "AtomString" would be unproblematic. The problem is the specific word "atomic" carries an expectation that the object be safe to access concurrently across threads without locks; I think that expectation doesn't exist if not for the "ic" at the end.

So hard to pronounce though! Why not UniqueString? It’s not quite as explicit but close enough.
