| Basically, the rule isn't whether the strings are equal, but whether they are handled verbatim without applying operations to them. The same trick fails with other types, including keys; adding e.g. a key variable to a list multiple times, results in one new instance of the key being counted for every addition. Same happens for integers, for example. But extracting them as lists still works. | Basically, the rule isn't whether the strings are equal, but whether they are handled verbatim without applying operations to them.
