Nevermind! I rediscovered the `inout`attribute.
Correct, inout applied to the function is actually applying to the 'this' parameter. Same as const or immutable functions as well.
Though if I may say so, I have no idea how `inout` is supposed to indicate "whatever the constness of a".
What inout does is look at the mutability of the parameter and transfer it to the mutability of the return type.
