Why not "hello" === "hello"?



I understand that strings are implemented as mutable types. But from a user’s perspective, strings are values, like integers are. Currently "hello" === "hello" returns false, but if it returned true, then things like these:

would be automatically fixed.


That’s why. I might be fixed in the future but it has never been the case so no one should be relying on it.


Also, it’ll not be an automatic fix. The generic fix is still https://github.com/JuliaLang/julia/issues/4648


You mean that a “patch” cannot be made for strings, so that === deviates from its general behavior and actually does the same as ==, only for strings?
