Issue #14105 has been updated by jeremyevans0 (Jeremy Evans).
`^` is used as the exclusive-or operator in many other programming languages including C, C++, C#, D, Java, Perl, PHP and Python.
If a user wants to use `xor` instead of `^`, they can always alias it manually:
~~~ruby
class Set
alias xor ^
end
~~~
In general I prefer that users add their own aliases. I don't think Ruby should add aliases unless the current method names are so bad as to be misleading, and I don't believe that to be the case here.
Note that the following core classes also use `^` for exclusive-or:
* Integer
* FalseClass
* TrueClass
* NilClass
One counterpoint is that Set already aliases `&` to `intersection` and `|` to `union`, so adding `xor` would be consistent in that sense.

Feature #14105: Introduce xor as alias for Set#^

----------------------------------------
Not sure if I should also add feautures for the `Set` class here or if I should do it somewhere else.
I would like to add a more readable method for the exclusive or, currently as `^` in set. It is in both mathematics, hardware and many other programming languages known as `xor`, so I think this will help to use it.
